Probably something amiss with your OS after the Upgrade. Some Windows Diagnostic tools to try...
First try System File Checker
Winkey plus 'X'
Choose Command Prompt (Admin)
Type sfc /scannow then Enter

It finds and fixes errors in Windows, but doesn't always report them. Run it and see if the fault disappears after re-booting your system
If corrupt files are found that can’t be fixed, try

Dism /Online /Cleanup-Image /RestoreHealth (Observe spaces before /)

Re-run SFC

To view CBS Log

findstr /c:"[SR]" %windir%\logs\cbs\cbs.log >sfcdetails.txt

Search C drive for sfcdetails.txt or navigate to C:\Windows\System32 and scroll down.
