Stuck at error after installing new graphics card

Does anyone know what i need to do to fix this error? I have been using hackintosh without a graphics card and without graphics acceleration but now i finally bought myself xfx rx6800xt and added the pikera boot-arg aswell. Now macos does not boot anymore after i installed the graphics card and boot-arg. I dont know what to do. Im using i5-12600k if that matters.
