Internal EFI not appearing

MacBook Air 7,2 (2015) with Sonoma 14.6.1. Runs great when booting from the flash drive and the OCLP EFI appears when holding down option if the flash drive with the installation is in. Tried many times to install OCLP to the internal disk, but without the flash drive in on boot, all I get is Macintosh HD in the boot menu, which can't boot without the OCLP EFI (🚫 icon). It seems to install fine but it's nowhere to be found. Tried several times. EFI partition is mounted and is at disk0s1.

TL;DR Can only boot with flash drive in. Any help is appreciated!
