I have a start date and country overhaul mod, and whenever I try to load it, upon initialization, the game crashes. The error logs aren't much help either, this is the error:

Update: I found out why it was crashing, when I opened error log, I saw that the focus trees and certain states were broken, states would have no controllers and focuses were just broken. But when I fixed this, it still crashed on "Initializing Game", and this was the error log.
