Thank for reporting back. Now we know that's it is not always working when using an Intel GPU at the same time. The meaning to wipe a driver is to use a tool like DDU (another app I made) to remove the driver. It does the job deeper than the usual uninstaller from AMD. Technically on the instruction page "First post" there should be a step 3.5 - (Reboot and open CCC again.) It was necessary for me on DVI connection or not all sub-keys would be created.
