have you tried the windows update troubleshooter?
its in settings/update & security/troubleshoot
probably shows on the Additional Troubleshooter page

see if this help
right click start button
choose powershell (admin)
type SFC /scannow and press enter
once its completed, copy/paste this command into same window:

Repair-WindowsImage -Online -RestoreHealth
and press enter

SFC fixes system files, second command cleans image files, re run SFC again if it failed to fix all files before you ran the 2nd command, as the 2nd fixes the files SFC uses to check system files, and restart PC

which version of win 10
right click start
choose run...
type winver and press enter
current version is 20H2
