Can't get past PCI Configuration Begin

No matter what I try, the furtherest I can get is:

[ PCI Configuration Begin ] IOPCIConfigurator::configure kIOPCIEnumerationWaitTime is 900 

I followed the https://dortania.github.io/ guide, reading each part carefully, a few times. Each ending with this same message. Any insight or suggestions would be highly appreciated.

My hardware is:

CPU: i5-8600K RAM: 32GB @ 3200MHz GPU: Flag to disable all but the iGPU is set (I have a RTX 3070) SSD: Samsung 970 Evo Plus 500GB (with most recent firmware) Samsung 850 EVO M.2 500GB Mainboard: Gigabyte Z390 Master USB ports were mapped All mentioned BIOS settings (if present) were set If I couldn't find a setting, then the appropriate config.plist flag was added USB: Made on a Mac with an EFI partition and the full installer downloaded
