I can also verify the latest version of the trainer crashes the latest Steam version of the game, I can avoid a F1 induced crash by pressing it ingame but the instant I try to enable any options the game insta-crashes. (Maybe the dev added 1001 anti-cheat triggers?)
I don't have the game installed anymore, but try using the trainer before the latest one. I think that one seemed to work... I don't remember, but I believe it did. So, it could be possible they have rolled back for the game. That's if, the game hasn't updated ever since.
