Sorry, I can't run your game as you have some mods that are savegame incompatible with the original installation.

I am unable to disable the background script as the problem occurs after I hit the End Turn button.
There is no way to stop the script after starting it. This is the way to disable the script in the first place: you need to load your game and click end turn without starting the script.

If there are any rebelling cities around the map, they could cause the crash. Take a look around (with toggle_fow) and if you see any red faces cheat them happy, using add_population settlementname -4000 until they're happy again.
