Hello, I’m Virginia an independent advisor with 20 years of expertise in fixing my own & friends’ PC problems.
Which Windows 10 build are you running - 1903, 1909, 2004 or 20H2 (Oct 2020)?
Right click on start & choose powershell with admin & enter:
DISM /Online /Cleanup-Image /StartComponentCleanup
DISM /Online /Cleanup-Image /RestoreHealth
Then restart the PC.
These will fix the problem.
If by some chance they don’t:
I recommend an in-place upgrade repair.
To repair Windows without losing any data then follow the instruction here:

This will also upgrade you to the latest version of Windows - currently 20H2 - if you’re not already running this..
In a nutshell you just download the media creation tool, run this & choose to upgrade now or if you are creating media on another PC you download the tool, run it & choose to create media for another PC, then insert the Windows 10 media (USB/DVD) in the problem PC & run setup from within Windows.
Please note a repair install is not a reset, this is a last attempt at repairing a PC without a clean install. If this fails to repair the problem then usually a clean install is required.
