OCS: no schema for Arch at index 6, context

I am trying to change from clover to Opencore on my already working Mojave hackintosh. I want to test Opencore before I upgrade my main rig.

The computer is a Broadwell i3 5005U mini pc. Works flawlessly with clover.

I am able to boot into Opencore and get to the installer screen from a USB. However, if I take the same EFI that works on the USB and use it on my already installed SSD I get this error at boot then it restarts to BIOS in a loop.

I followed the vanilla guide through multiple times and thought it would just work fine but it won't even boot.

I can't find anything on google relating to this error. Does it 7 times.

Maybe something with APFS since the USB works? I have no idea.

Any suggestions are appreciated.
