Hi Rich,
My name is Igor, it's a pleasure for me to help others and I'll try to help you.
Unfortunately, this may mean a hardware or software problem.
Please repair system files by
DISM.exe /Online /Cleanup-Image /RestoreHealth
command from Windows Terminal (admin) environment.
Run PowerShell as administrator and run Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"} Note: Several red warnings may appear when running this command. Ignore them. It's normal.
If this will not help, run Windows memory diagnostic tool and switch it to extended mode when it starts (F1 key). Note, test hang at ~21% for more than 2-3 hours means memory error too.
