Could you provide some more details on the problems you're experiencing?

For what particular reason did you reinstall Revit?
-Did the application freezze, become irresponsible, critical error?

Do you have third-party apps installed?

What Windows version are you using and is it a network or named user license?

I am happy to help you if you can provide more info.

After doing a quick search on ''missing schema'' I found this potential solution for your error.

Basically open the Autodesk desktop app and click My updates.
Or
If this doesn't work manually install RevitUnitSchemas.msi , it is located on C:\Autodesk\WI\Autodesk Revit 2021\x64\RS 
Don't forget to Reboot

If this helped you don't forget to accept as a solution.
