5700XT Freezing Issue

I recently installed a 5700XT into my Hackintosh. It was working fine with my previous RX580, I hadn't tested it hard underload, but it never froze. However, when I upgraded to the 5700XT the computer is freezing more often as I use it for professional workflow. The system doesn't go black screen, it just freezes and the mouse freezes also. I have to shut down the computer and reboot to get it to work again. Should I just switch back to a RX580? I really prefer Catalina interface wise, so would rather not update to Big Sur. Does anyone know of any solutions to solve this?

Set Up:
Catalina 10.15.7
OpenCore
SMBIOS iMac Pro 1,1
i9-9900k
Z390 Designare MB
32GB DDR4 3200 MHz
