Hi BadgerMole
How are you? I hope you are doing good.
Welcome to Microsoft Community. I am Juliet, an independent advisor. It's my pleasure to help you today. I know how frustrating this may be for you but I'll do my very best to help you :)
I would suggest you try to run SFC
In the search box on the taskbar, type Command Prompt, and right-click or press and hold Command Prompt (Desktop app) from the list of results.
Select Run as administrator, and then select Yes.
Type DISM.exe /Online /Cleanup-image /Restorehealth (note the space before each "/"), and then press Enter.
(Note: This step may take a few minutes to start and up to 30 minutes to complete.)
After you see a message that says "The operation completed successfully," type sfc/scannow (note the space between "sfc" and "/") and press Enter.
After you see a message that says, "Verification 100% complete," type exit.
I hope it helps! Let me know the results.
Please Let me know if you have more questions or the above method didn't work for you, I'll be more than happy to assist you further :)
