MacBook Pro (Early 2015) running Sonoma via OCLP won’t boot after root patch – need fix without reinstall

Hello, I’ve got a MacBook Pro Retina (Early 2015) that was patched to run macOS Sonoma using OpenCore Legacy Patcher. Yesterday it was a bit slow and graphics looked weird, so I ran the Post-Install Root Patch in OCLP (same thing I did before when this happened).

After that, my Mac won’t boot, sometimes I get the Apple logo, sometimes not. Mostly it just stays stuck at a weird loading screen (photo attached). I tried force shutting down, waiting overnight, same thing.

Problem: I don’t have the OpenCore USB the guy used to install Sonoma for me. I really need to get this working TODAY without wiping or reinstalling macOS.

Any way to reapply the root patch or boot into Sonoma without the USB? I can get into Internet Recovery but that would reinstall Catalina, which I’m trying to avoid.

Any help would be a lifesaver🙏
