Same issue on two computers. The first runs win11 22H2 build 22622.575 and the second win10 build 19044.1889.
The problem on the Win10 pc leading to kernel critical errors and system restarts once per day. Disabling Microsoft signin assistant service eliminates the errors AND the system crashes but has major side effects (problems with Office 365, cant sign in on Game pass etc).
At least i haven't experienced system crashes on the win11 pc.
Thank you!
Yes, as you and others report, disabling the MS Account Signin Assistant service does indeed stop the error from occurring, but also prevents some apps from signing in properly. In my case it's MS Edge, but Office 365 would be big as well if I used that.
