No video output

I was recently trying to install Manjaro on my pc using the live USB media, but it had always crashed and would go black after a while
I found that the root issue was my GPU (Radeon Rx 570), when i removed the card and used the iGPU on my CPU (Ryzen 5 3400G) everything worked fine. But I don’t want to have to remove my GPU just to run it on my system.
what should i do?

I can provide more details if needed

CPU: Ryzen 5 3400G
GPU :Radeon Rx 570
Kernel 5.9 (but i have tried lower kernel’s such as 5.4)
Pre and post install
