Cannot crate car type bug

What happens is is sometimes the game decides to not load a specific car type, and my game always cries when this happens. What I mean by that is that it doesn't generate specific car types (420 - the taxi - WHICH I HAVE NO MODS RELATED TO) so I don't know why this happens. I'm still able to play, but at great risk of crash if I respawn because sometimes the car error messages flood my chat until the game crashes.

Also, if I enter the game without an anti-crasher, it always crashes upon start-up - here's the error message for you tech savvy people:
