os.scandir is a simple wrapper around FindFirstFile/FindNextFile.  If FindFirstFileW("R:", "*.*") sets the file-not-found Windows error code, then that will be turned into the exception that you see.

You might want to try os.scandir("R:\\").  Your issue could have something to do with the current directory for the R: drive not being well-defined.
