Solved
Zerbu's all worlds are residential mod seems to be broken.
With that mod in, whenever I open the game, better exceptions pops up with a UI exception. I tested with removing mods and it lead me to all worlds are residential. I have the most recent version of better exceptions as well, so it's not just that I need to update that.
It's back on the list as broken, and I'm going to update how it's broken now that there are more reports.
