XFX Radeon RX 580 GTS XXX Edition Was working fine in Mojave but does not work in Catalina. I had a little glitch in the beginning where I had to flip the little switch on the card, but then it worked fine, but now that I've upgraded to Catalina, it will not work at all. Any ideas? I've heard something about maybe needing RadeonDeInit, but I don't know how to install that if that is the fix.

I had the same issue what you can do is get the hacking tool and fix it up real quick does your card have 3 DP and 1 HDMI you kind of have to set the ports in the hacking tool and then it should work fine search hacking tool and 580 should see a lot of post on it
