For the error, you should be able to safely delete the C:\ProgramData\SIL\WritingSystemRepository
folder. Paratext will recreate it, and other SIL applications (e.g. FLEx) should also work a similar way.
That is the path to the code files for the code that is having the error (in the stack). You can ignore all that - it’s just useful for the Paratext team to try figure out where problems are occurring.
