High Sierra not booting after any Security Update

Hi everyone, recently I installed High Sierra via OpenCore. Everything boots, successful install, EFI on drive, but when I try to install a security update, selecting macOS from the OpenCore boot picker just sends me back to the picker. 🥲 I reinstalled (Third time) and don’t want to have it happen again. Any tips on why it’s not booting? Vesa mode is on, and it’s not just a black screen, it sends me back to the picker. Currently I’m on version 10.13.16 (17G66), and in order to install Nvidia Web drivers, I need to be on a higher version. My goal is to be on the latest.

Thanks!

OpenCore 0.66

(Let me know if you need the config.plist ;)
