Okay, so I've run into a very strange glitch. I'm not even sure how to describe it other than I believe that the cell has loaded and all walls and objects are present, but strangely everything seems to not have their textures loaded. Walls, clutter, npcs, you name it; just about everything except a few torches and light sources are completely invisible. Not even Exclamation Points, placeholder textures, or purple objects See screenshots for what I mean:
In case you can't tell, this is supposed to be Labyrinthian. Specifically, Labyrinthian Tribune, where the boss fight with Morokei is supposed to happen as part of obtaining the Staff of Magnus for the College quest. I also have Lydia and Meeko with me in the cell; they too are somehow invisible even though can see them and enemy draugr using detection spells. What is perplexing is that this is the only cell I've had this problem in. I exit through the door and the prior section of Labyrinthian loads without issues...everyone and everything has their textures back and are visible. Outside of this dungeon, the only real problems I've had with my current playthrough are random ctds around Whiterun. This is the first time I've ever encountered a situation like this in dozens of playthroughs of Oldrim or Special Edition.
Load order, after LOOT:
