OpenCore Boot Menu Loop

I’m using a hackintosh pre-done EFI specifically made for the Dell XPS 9500/Precision 5550 made by jkbuha (google it along with GitHub) but every time I boot from the usb to the OpenCore menu, select the third option (external) (dmg) it does its thing, and then loops back to the menu again. I’ve done everything right I’m sure, put the 2 files in the usb, EFI and macOS Sonoma from the OpenCore Install guide. And make sure to set the BIOS settings correctly to what’s on jkbuha’s github page. I attached some images below. (I did use the clear cram option prior to taking the photos.)
