I am running W11 pro - 2H2 - and started to see this issue a couple of weeks ago when - or so I assume - 2H2 was installed. Now the system restarts every night (The previous system shutdown at 2:56:33 AM on 6/5/2023 was unexpected.) and does so in such a way that some running jobs (e.g. Acronis backups) hang until I present myself to the laptop, it recognises me and starts up. I assume that the system is waiting to log onto my Microsft account.
I know see continuous events telling me of errors with the BonjourService, Microsoft-Windows-ModernDeployment-Diagnostics-Provider, Printers (my only printer is local), etc, etc, etc.
The system is now so busy alerting - it is probably adversly impacting the user-experiance. I will shortly contact Microdost but - if the other responses are anything to go by - I doubt anything will come of it.
