did you do a safe mode/DDU uninstall, or did just install the studio drivers over the top? even the “clean install” option leaves ■■■■ behind that can mess with driver updates let alone different types of drivers.
there is a misconception on what clean install actually does - it doesn’t clean the previous drivers, but it resets the previous existing user settings and profiles … that’s it
it doesn’t do clean install; it doesn’t remove leftover files; it doesn’t remove leftover registry entries
