Maximum containment area not loading any fix

At the final part of the maximum containment area where you fight the Proto but the area doesn't load in even in the cutscene the room Kurtis runs into is pitch black and does not exist.

Has anyone else experienced this, did you fix it? Am I going to have to start over? 🥲

Things I've tried are reloading the save, quitting to main menu and opening a new save then loading into my save, just reloading the area by leaving that zone but the zone before that is also black and empty. I've quit to desktop and opened it up still nothing.
