Disconnect the Internet from your computer to prevent it from installing a different GPU Driver than the one you are installing.
Use Windows Control Panel -Uninstall Feature to uninstall all AMD Drivers and software. Then use DDU (Display Driver Uninstaller) in safe mode to completely eliminate all traces of the old AMD drivers and software related to the GPU.
