Failed to get local signing public key on Dell Optiplex 7450 AIO

hello, I am trying to install macOS Monterey on my Dell Optiplex and I can't get it to work, it stops at "Failed to get local signing public key" and displays the prohibited sign with apple.com/startup and the verbose text is glitched.

my dell is a Optiplex 7450 AIO with a i5 (Skylake) and intel hd 530 graphics.

I followed a tutorial online and the open core website according to my processor and everything went good except the lilu.kext and virtualsmc.kext that I needed to get from the GitHub repos and could't download from opencore configurator, but it still doesn't work

i saw on this subbreddit that i should try a usb 3.0 port and it still does not work

here's my EFI i made

this is my first hackintosh so any advice is welcome
