Infinite black screen after loading screen when entering Skyrim

[TruestNim]

Hi,
I've been playing on my modded save for some time now, and didn't have too many problems (they're usually small stuff that's quick to fix). But recently I picked up the Eldergleam quest, and upon trying to leave the cave I get a normal loading screen, then an infinite black screen with sound. I've tried waiting it out, then I did some research, and none of the fixes I found online worked (though a lot of them are for oldrim). I tried my own troubleshooting by loading a previous save (I can go in and out of skyrim just fine), but as soon as I'm up to the eldergleam cave in terms of progress, anytime I try to go to skyrim from any room my loading screen freezes. I tried teleporting myself to NPCs outside the cave, and it works fine if they're outside, but if they're inside and I try to leave the building, I get an infinite loading screen again. I've also installed various fixes from nexusmods and such, none of them seem to have made a difference. Anyone know what causes this ?
