Up until an hour ago, my game was working fine. I could load it, could play it. Everything was perfect.
I quit out of the game, shifted two mods down two places (cleaner settlements, and cleaner sanctuary) nearer the bottom of my load order, and now my game doesn't load at all. I went to load the game, it launched through steam, took me to the loader, took me through the 'now detecting your settings' thing.

If I click the F4SE shortcut on my desktop, it brings up the Fallout launcher, which it didn't do before. If I launch through that, the game crashes. If I launch as administrator, it goes to a black screen a third the size of my desktop, then crashes. I've restarted Steam, restarted my computer, done everything I can think of, and nothing.

I have no idea why it stopped working when all I did was move two things down maybe two places in my load order. I haven't updated anything else, installed anything else, changed anything else.

Here's my load order, if that helps. Here's a screenshot of what happens when I try and load it. This is bizarre, and weird, and I genuinely have no idea what's caused this. All mods are up to date, and were working perfectly fine, right up until they weren't.
