Hello timfg,welcome to the Microsoft community, I'll be happy to help you today;
I understand that you are having problems with each update performed in Windows 11;
Are you using a Microsoft administrator account to access Windows?
Initially I recommend that you try the solutions below;
Press Windows key + i and go to Accounts;
Click Sign in options;
Enable the option "Use my sign-in info to finish setting up my device after an update or restart" and "Automatically save my restartable apps when I sign out and restart them after I sign in";
Then run the system file checker;
Click on the Windows search bar and type: CMD
The search result for CMD (Command Prompt) will be displayed, click Run as administrator;
Copy and paste the commands below by pressing Enter after typing each command line:
Sfc /ScanNow
DISM /Online /Cleanup-Image /ScanHealth
Dism /Online /Cleanup-image /RestoreHealth
Check if the issue still persists after an update;
Hope this helps, see you soon!
