Crash when resting in the underdark

The game crashes when resting in the underdark area; I don't know the error cause it doesn't come up with one.
Any ideas how to fix it?
Here's the save file.

I used mods, but Even if I tried to uninstall all of them it still crashed.
I even tried to empty my inventory, no use...

Oh yeah, the slayer form disappeared too.
