Possibility A: The driver is just not loading right. So try the following and sorry in advance for wasting your time if this does not work.
Have the driver you want to install downloaded.
Run DDU from wagnardsoft dot com, from safe mode with the Internet disabled. Just unplug or turn off the router or modem is fine.
Restart after running DDU to normal but still have the Internet disabled.
Then install the driver again don't use express settings. Use Factory Reset and that should get you going again.
Possibility B: The new driver has a bug.
In Radeon Settings there is a Bug Report tool you can submit the issue or
You can contact AMD support here: https://www.amd.com/en/support/contact-email-form
--------------
Then go back and DDU and return to a driver that worked and use Factory Reset when installing.
Good Luck!
