I've had problems with underground hideout in the past, By looking at it it looks like its that, i would disable that mod and see what happens

What i do is go into task view right next to windows search bar, and go to a different desktop open task manager there and close it using that

On Nexus there should be a download history you can use to find the old mods you had, other then that i don't think there is much
