Boot goes to a black screen on a RX 5500 XT

Recommended Posts

Hi, I'm trying to boot the USB install of the Catalina 10.15.3 image in my pc, but after a while, it goes to a black screen and restarts after a long while.

My pc:
Mobo: Gigabyte Z390 Gaming X
CPU: i5 9400f
GPU: SAPPHIRE RX 5500 XT 8gb

Any help would be really appreciated!
