Hello, mate, and welcome aboard (wooo, logged back in after years just for this)! My troubleshooting hot tips aren't quite sharp these days, but I'd recommend you to hop into our Discord server for better and more prompt help than what you might find around here, through this link:

Regardless, I don't suppose your controller might be the culprit of the issue you're prompting - have you tried booting up the game with it disconnected just to be sure? That error was pretty typical when you deleted a car mod that happened to be the last you played with, deleting the "players" folder usually did the trick, though I'm not aware if it could also have something to do with mm2hook, either. Try your luck at Discord!
