[OC 0.6.3] High Sierra 10.13.6: Hanging on "Can't get kextd port." during boot

I'm a first time hackintosher(?), and I've hit a bit of a block. I'm trying to install MacOS 10.13.6 with OpenCore 0.6.3, and I've gotten through to the disk utility to format my drive to MacOS Extended (Journaled) etc., but when I try to boot so I can properly install it, it hangs on "Can't get kextd port.".

I've heard that Asrock can be a bit finicky, but there's some people on this sub with successful Asrock builds that give me hope. I've checked my BIOS settings, and run my config.plist through the sanity checker to the point of insanity. I think I just need some fresh eyes and experience
