Thats what I did, fresh Windows 10 reinstall with nVidia GPU removed from mtb. It worked few days with nVidia pluged back after AMD drivers were all in place and Adrenalin up and working but unfortunatelly it was for short time.
With Windows 11 it worked month or more with nVidia and integrated AMD graphics card then start throwing error messages whenever I tried to acess Adrenalin. After trying everything found online, on Microsoft and AMD sites I decided to reinstall Windows 10 this time. As you can understand, happy and joy were very short.
