[HELP NEEDED!] Black screen after text when trying to boot into Sonoma installer, what else to troubleshoot?? (Comet Lake)

SETUP: Dell Precision 3640, i9-10900 (Non-K), Intel iGPU (No dGPU installed), iMac20,2 SMBIOS, PLIST: https://files.catbox.moe/6cxwkm.plist, OPENCORE LOG: https://fikes.catbox.moe/zty3jg.txt

First time building a Hackintosh, coming from Arch Linux

I based my installation using this premade EFI: https://github.com/dragonflylee/hackintosh-dell-precision-3640-comet-lake-opencore, i followed the instructions in the readme and changed CFG Lock to off and set the DVMT value to 64M, with this configuration when i selected the Sonoma installer it would just send me back to the OpenCore main menu, so i changed some settings according to Dortania's guide for Comet Lake and tried some of the steps in Dortania's troubleshooting guide, at least the ones that mada sense for my issue and the farthest i've gotten is a black screen after the text when selecting the Sonoma Installer.

I checked against https://velicovicdj.github.io/OC3 to find any inconsistencies, the only ones pointed out are because they're required to be set to different values because of my specific setup or say "There's no schema for this key, Check your OpenCore version." which i imagine is just a version difference since i'm using OpenCore 1.0.5 and the checker is for 1.0.3

It also says that my MLB is set incorrectly, i let GenSMBIOS do the work so i don't know how that could be it

This seems to be a common issue but i'm really stumped at the moment, any help or guidance is needed, thank you!!
