Hello everyone, I'm at a loss here. I'm trying to setup my first AMD hackintosh and I can't even make it to the installation screen. When I select the "OPENCORE (external) (dmg)" option at the opencore menu, nothing happens for ~15sec, then some text appears at the left of the screen and 2sec later the text disappears and a prohibited sign appears in the middle with the caption "support.apple.com/mac/startup" below it. And after another ~15sec it returns to the opencore menu.

I have carefully put together the EFI by following the Dortania guide and I've been trying to fix it for the past week but nothing works.

Things I've tried so far:
Different USB ports, different USB flash drives
USB Mapping, both native and non-native classes using USBToolBox
Mmio Whitelist
Using the kexts from the Dortania troubleshooting section for the prohibited sign (XLNCUSBFix.kext, DummyUSBXHCIPCI.kext etc)
Rebuilt the EFI like 10 times

I've attached my EFI and last opencore log so you can take a look, the big block of text at the end of the log is what appears right before the prohibited sign.

My specs are: Asus TUF B850-Plus, Ryzen 7 9800X3D, GPU 6900XT, 64GB DDR5 RAM, SN850X SSD.
