You also might want to check out the bug reported here:
it was fixed and the last two comments discuss how to handle it in Windows:

This fix is in R-4.2.1 Patched (I don't know if it has made it out to the full distribution) and works in my 'corporate' environment. Perhaps it also applies to your environment.
