Hi, Adam Thunder
Welcome to Microsoft Community.
I understand your frustration with the error you are experiencing on Windows 11. This is especially true when it affects your ability to save progress in a game. However, we need more information to pinpoint the issue, what game are you playing that you are experiencing this issue with? Could you please provide us with an image so we can analyze it further? Thank you for your understanding and cooperation!
Best Regards
