Inifinite loading screen when starting new game - Steam Deck

So I'm having trouble getting my game to work at all, and it's hard to get a crash to even get a crash log.

Here's what I got when trying to load my latest save though: https://pastebin.com/Q3RAXgQC

The save should work; I was getting crashes before in that save, but it loaded into the game at least.

If I try to make a new game, I just get an infinite loading screen.

If I try to load into whiterun via console commands, I get a series of popups about SKSE not being installed (even though it is) and the screen just stays black.

Before, when the game was still loading, most of the crashes were caused because of animation errors, so I ran Nemesis to try to fix it. Since then, I can't get into the game at all.

Any advice? Thanks!
