So this issue has been going on for almost a month now,event viewer is showing tons of these errors,i have 3 windows 10 installations and in each the error is there.Even tried to do a clean install on my main pc today to see if it would go away but to no effect.
This is the error:
Autopilot.dll WIL error was reported.
HRESULT: 0x80070491
File: onecoreuap\admin\moderndeployment\autopilot\dll\dllmain.cpp, line 178

I searched a bit trough the comunity and found out that there are tons of people having the exact same problem.

2022-11-07T20:34:30+00:00 I have a similar issue but on line 138. I do not have the 22H2 Windows 11 update installed. The problem started 10/24/2022. There are additional errors in Server, DbxSvc, DistributedCOM, etc. , but similar errors were occurring before this ModernDeployment-Diagnostics-Provider error started happening. A new problem is that yesterday and today my relatively new machine crashed and had to be forcibly rebooted. I can't prove this is related, however.
Did you by chance perform an update using Windows update on or before 10/24/22?
