Booted up Cosmic Invasion on Game Pass, smashed through the prologue… and then nothing? No achievement pop. No online play. Just an endless “Sign in” screen staring back at you.
Yeah — you’re not doing anything wrong.
A lot of players are running into achievement bugs and online sign-in issues on the Game Pass PC and Xbox versions of Cosmic Invasion, especially during those first few sessions. You finish the prologue expecting that satisfying achievement unlock, only for the game to stay completely silent. Jump into online modes and suddenly you’re stuck watching a loading message loop forever.
The good news? These issues aren’t usually tied to your skill, progress, or hardware. They’re mostly linked to how the Game Pass version handles sign-ins, cloud saves, and achievement syncing. And in many cases, the fixes are surprisingly simple once you know where to look.
Here’s what’s actually going on — and how to get things working.
Quick Fix (Try This First)
Before diving deep, run through this quick reset. It fixes the issue for a surprising number of players, especially those experiencing achievement sync problems or an endless sign-in loop on the Game Pass version. These steps might seem basic, but they help force the Xbox services to refresh your account connection and resync properly with the game.
Close Cosmic Invasion completely, making sure it’s not still running in the background. Next, sign out of the Xbox App rather than just closing it. Once you’ve done that, restart your PC or console to clear any cached sign-in data. After the reboot, sign back into the Xbox App using the same account tied to your Game Pass subscription, then launch the game again directly from the app.

Achievements Not Unlocking in Cosmic Invasion (Game Pass)
What players are seeing
Prologue achievement doesn’t pop, even after finishing it cleanly. Achievements appear in the list but never actually unlock, no matter how many times you meet the requirements. In some cases, progress is clearly completed in-game, but Xbox simply doesn’t register it at all. There’s no error message, no warning — just silence where that achievement notification should be.
This seems to be a Game Pass–specific issue, mostly tied to how the game handles first-launch save files and cloud synchronization. If the initial save doesn’t sync correctly with Xbox services, achievements can fail to track from that point onward. It’s frustrating, but the issue isn’t permanent, and for most players it can be fixed without waiting for a patch.
Fix #1: Delete Cloud & Local Saves (Most Reliable)
This is the fix that works for most people — but fair warning:
This resets your progress
The reason this works is because achievement tracking issues on the Game Pass version are often caused by a corrupted or improperly synced first save. By removing both the local and cloud data, you’re forcing the game and Xbox services to create a clean, fresh save that can properly track progress and achievements again.
On PC (Xbox App):
Open the Xbox App
Go to Cosmic Invasion
Select Manage
Open Saved Data
Delete both local and cloud saves
Relaunch the game
Replay the prologue
Once you complete the prologue again, many players report that the achievement unlocks immediately, sometimes the moment the final scene ends. It’s not ideal to lose progress, but if your achievements are completely stuck, this is currently the most reliable fix available.
Fix #2: Start a Fresh Save File
Not ready to wipe everything?
Create a new save slot
Replay the prologue
Check if the achievement unlocks
This method works because, in some cases, achievements only bug out on the first save file created when you launch the game for the first time. If that initial save doesn’t sync correctly with Xbox’s achievement system, progress tracking can break entirely for that file. By starting a fresh save slot, you’re essentially giving the game another chance to register achievements properly without deleting all your existing data. For many players, this is an easier workaround that still triggers the prologue achievement without having to fully reset their progress.
Fix #3: Check for Silent Unlocks
Sometimes the achievement actually unlocks… it just doesn’t pop. This can make it seem like nothing worked, even though Xbox has already registered it in the background. The notification fails to appear, but the achievement itself may still be counted on your profile.
Open the Xbox overlay and head straight to the Achievements section. From there, check whether the prologue or other achievements are already marked as unlocked. If they are, the issue is purely visual and not related to your progress.
If the achievement shows as unlocked but didn’t pop, restart the Xbox App to force a full sync with Xbox services. This often refreshes achievement data and clears up display or notification glitches.

Cosmic Invasion Sign-In Stuck / Online Not Working
If the game just sits on “Sign in” forever or online modes won’t work, you’re dealing with a different (but very common) issue. This problem is affecting a lot of players on the Game Pass PC and Xbox versions, and it usually isn’t caused by your internet connection or console performance. Instead, it’s often related to how the game communicates with Xbox services during launch or how your account is authenticated through the Xbox App.
Typical symptoms
Endless sign-in loading screen
Multiplayer unavailable or completely greyed out
“Application access is restricted” error
When this happens, the game fails to properly verify your account, which blocks online features from loading correctly. The good news is that this issue is usually fixable with account refreshes or service checks, rather than needing a full reinstall.
Fix #1: Check Xbox Services
Before blaming the game itself, it’s always worth checking if Xbox is having a bad day. When Xbox services go down or experience partial outages, games that rely on online authentication and multiplayer features—like Cosmic Invasion—can get stuck on the sign-in screen or block online modes entirely, even if everything looks fine on your end.
If any of the following services are down or unstable, online play won’t work properly:
Xbox Live Auth Manager
Xbox Live Game Services
Xbox Multiplayer Services
If there’s an outage, there’s nothing wrong with your setup and no fix you can apply locally. In that case, all you can do is wait it out until Xbox restores the affected services and the game can connect normally again.
Fix #2: Re-log into Xbox App (This Fixes Most Sign-In Loops)
Sign out of the Xbox App
Sign out of the Microsoft Store
Restart your PC or console
Sign back into both apps
Launch Cosmic Invasion directly from the Xbox App
This usually clears the endless sign-in loop by forcing Xbox services to fully refresh your account session and re-verify your Game Pass entitlement. Sometimes the Xbox App and Microsoft Store fall out of sync, which can prevent the game from confirming your sign-in properly. Restarting your system after signing out helps clear cached credentials, and launching the game directly from the Xbox App ensures it connects using the correct account and permissions.
Fix #3: “Application Access Is Restricted” Error
This one’s almost always a Game Pass entitlement issue, not a bug you caused. When this error appears, it usually means Xbox can’t properly verify that your account has permission to launch or access online features for Cosmic Invasion, even if you’ve been playing it without issues before.
Try this:
Make sure your Game Pass subscription is active
Confirm Cosmic Invasion shows in your library
Launch it directly from the Xbox App
Avoid using desktop shortcuts
These steps help ensure the game is being launched with the correct account and permissions. If the error still won’t go away after trying this, the problem is most likely account-side, which means it will need to be resolved through Xbox services rather than with an in-game fix.
Extra Things Worth Trying
If nothing above worked, these are worth a shot. While these steps aren’t guaranteed fixes, they can help resolve lingering connection or authentication problems that interfere with achievements or online features. In some cases, background software or network settings can quietly block Xbox services without throwing a clear error, which is why these checks are still worth doing.
Restart your router to refresh your network connection and clear any temporary routing issues. Turn off any VPN, as VPNs can interfere with Xbox authentication and online connectivity.
Temporarily disable your firewall or antivirus software to make sure it isn’t blocking the Xbox App or the game itself. You can also repair the Xbox App by going to Windows Settings → Apps → Xbox App → Repair, which resets app components without deleting data. Be sure to reboot after each major step to ensure changes take effect properly.
Is This a Known Problem?
Yep. Players across PC and Xbox are reporting the same set of issues, especially those playing through Game Pass. Reports consistently mention achievements not unlocking on Game Pass, online sign-in failures that leave the game stuck loading, and save-file related bugs that prevent progress or achievements from syncing correctly. These problems are showing up across different hardware setups, which makes it clear this isn’t an isolated case or user-specific mistake.
Interestingly, Steam players don’t seem to be affected nearly as much, which strongly points to a Game Pass–specific issue rather than a core gameplay bug. That suggests the problem lies with account authentication, cloud saves, or Xbox service integration, rather than the game itself.
When You Should Contact Support
If you’ve already deleted cloud saves, replayed the prologue, and re-logged into the Xbox App, and things still aren’t working, it’s time to escalate the issue. At this point, the problem is likely no longer something you can fix locally, and continuing to repeat the same steps probably won’t help. Reaching out to support can feel frustrating, but it’s often the fastest way to resolve account- or service-level problems.
Contact Xbox Support for issues related to achievements not unlocking, account authentication, or cloud save syncing. You should also contact the game’s developer or publisher to report Game Pass–specific bugs that may require a patch or backend fix.
Have this ready before you reach out: your platform (PC or Xbox), the exact error message you’re seeing, and a clear list of what you’ve already tried. It’ll save you a lot of back-and-forth.
Bottom Line
✔️ Achievements not unlocking? → A cloud save reset usually fixes it.
✔️ Prologue achievement missing? → A fresh save is often required.
✔️ Sign-in stuck or online broken? → It’s usually an Xbox App re-login or Xbox service issue.
❌ Rare cases need Xbox Support help.
Annoying? Absolutely.
Fixable? Most of the time, yeah.
The key thing to remember is that these issues aren’t caused by how you’re playing the game. They’re almost always tied to Game Pass authentication, cloud saves, or Xbox service syncing. While it’s frustrating to jump through a few hoops just to unlock achievements or play online, most players are able to get everything working again with one of the fixes above. In the rare cases where nothing works, support can usually sort it out — it just takes a bit of patience.
