GPU error possibly drivers?

Hello, nice to meet you. I have a problem when installing Bazzite which is that I do not get video with my AMD RX 640 4GB GPU. This happens after installing the system, I uninstall my GPU from my motherboard and start with the video output of my motherboard and there it works and gives video. So what I did was put the default video output in my BIOS to be my motherboard and not my GPU so that I can have my GPU connected to my motherboard and see if Bazzite recognizes it, which it does.... I try updating everything with ujust update but even that does not work. If there is someone who can help me I would appreciate it.
