Welcome to Microsoft Q&A.
Reinstalling updates may not offer help to solve problems caused by system files. You can download an ISO for in-place upgrade if reinstalling updates cannot fix your issue. In-place upgrade will upgrade your system without erasing your data and files. The steps are as follows:
2) Double-click the ISO file to open setup.exe
3) Choose not right now in the pop-up menu
4) Click change what to keep and choose save all datas to start installation:
Best regards,
Molly
