WTF NVidia????? Login now required in GeForce Experience

It probably checks the graphics driver version, but perhaps not the USB-C one you were seeing erroring. I would reboot and run nvcleaninstall to get everything installed properly. If that doesn’t work then reboot to safe mode, run drivercleaner, then reboot and nvcleaninstall again.

Incidentally, always use nvcleaninstall, it gets rid of Nvidia telemetry and other crap.

Hey, this program is neat. Thank you!

Yep totally worth using, it downloads the drivers for you and everything.
