Windows 11 has been on 21h2 builds thus far and keeps trying to install updates to 22h2 which fails with an error, either when run through windows update, or run externally. All the usual Windows Update resets and checks have been tried. This has now happened in excess of 30 times.In general the repeating error is:ACCESS_VIOLATION occurred at 0x00007FFBABA1FAA9 in C:\$WINDOWS.~BT\Sources\migcore.dll +00000000002AFAA9.This error is reported in the setupact.log located at C:\$WINDOWS.~BT\Sources\Panther\setupact.logSetupDiag.exe zipped logs attached.Net result is system won't upgrade to 22h

Cannot update Windows 11 to build 22h2

Need more help than support web site offers. I would like to update a Windows Pro 21h2 to 22h2.

I've tried every suggestion at Troubleshoot problems updating Windows - Microsoft Support short of "Perfrom a clean installation of Windows 11." That list is comprehensive and includes everything I would have thought of on my own and then some. None of the troubleshooting suggestions solved the problem. The system in question is a Lenovo ThinkCentre M90n desktop running Windows 11 Pro Version 21H2.

In addition to all the steps at the above link, I've also tried installing by using Windows 11 Installation Assistant. Installation Assistant downloads and goes through the long installation process. But then very shortly after the reboot starts, it says, "Undoing changes" and boots back into the old build.
