I'm having the same issue with my ASUS TUG gaming laptop, windows 11.
Here's what I tried so far:
ctrl ald del task manager does not work, the only thing I could do is open safe mode
1st time:
Tried repair - said it failed
Tried uninstalling latest updates - did nothing.
Tried restore point - managed that to work, copied all of my files just in case, ran windows update again then restarted, when booting up it said "please don't close updates are under way" - tho it was booting up as usual and there were no updates that were being installed it just gave the usual login screen, and after logging in got same error.
This time my desktop loads (except the bottom windows menu is not visible/gone) and everything looks alright for 2-3 seconds then the white screen appears again.
Tried repair - this time it didn't show fail error but still did nothing.
Tried uninstalling the update - this time it gave an error that it failed.
Tried restore point - 1st time failed, second time there were no restore point at all.
When shutting down it sometimes gives this error: ArmouryCrate.AppServiceBridge.exe - Application Error
The application was unable to start correctly (0xc0000142)
There were 2 windows updates and one other update that didn't say windows but some other BS, here are the names of 2 of them:

KB5034765
