Try these steps in this order:
- Confirm the same Microsoft account is signed in everywhere.
- Open the Xbox app and verify the profile is signed in.
- Open Microsoft Store and make sure it shows the same account.
- Game progress syncs through the Xbox profile and cloud saves.
- Update Windows.
- Go to Start > Settings > Windows Update > Check for updates.
- Install any available updates, then restart.
- Update Microsoft Store apps.
- Open Microsoft Store.
- Go to Library > Get updates.
- Let Microsoft Store and related apps finish updating.
- Repair or reset the affected apps again, including the related sign-in components.
- Go to Settings > Apps > Installed Apps.
- For Xbox app, Microsoft Store, and Gaming Services, open Advanced options and select Repair first.
- If needed, use Reset.
- Clear stored Xbox sign-in credentials.
- Open Credential Manager.
- Select Windows Credentials.
- Under Generic Credentials, remove entries that start with or contain Xbl.
- Restart the PC and try signing in again.
- If the issue appears to be account-specific, test in another Windows user profile.
- Go to Settings > Accounts > Family & other users.
- Add a temporary local user.
- Sign in to that profile, then open Microsoft Store and the game and try signing in there.
- If it works in the new profile, the problem is likely with the original Windows profile cache or account token state.
- If Microsoft account sign-in itself starts failing anywhere, use the Microsoft sign-in helper.
- The sign-in helper can identify account problems and guide the next steps.
If the game still fails to sign in after these steps, the supported next step in the available guidance is to use the game’s dedicated support channel for known issues or submit a request there.
