Answer 1

Please share your CBS logs for analysis. To collect the CBS logs, open admin PowerShell and run:

GCI -Path 'c:\windows\logs\cbs', 'c:\windows\inf\setupapi.dev.log' | Compress-Archive -destination (join-path ([environment]::GetFolderPath('Desktop')) \CBS.zip)

This creates a file named CBS.zip on your desktop. Share it on OneDrive or GoFile.io and post the link here.
