EDIT #1: Tried disabling all other mods; still crashed.
EDIT #2: Solved: Auto Research crashed when it completed Electronics when I had "Announce completed research" turned on. I turned it off and it works fine even with all other mods installed.
Auto Research is crashing the game when it completes a research. I think it's because it's trying to start a research illegally or is looking for a research that doesn't exist (modded). Here's a list of the mods i'm running:
