Playing with my late game, a pogrom from the Spartans, resulted in a CTD. The latest ruleset hot-fixes were applied.
End the turn in the attached save game. I suppose it's the map that's creating the problem. I share the save just in case it's something else.
EDIT: As suggested before, restarted the game from before landing the pogrom, and eventually a new map was loaded. So far no problems with the new map.
