Ok I can't really pinpoint it. It wasn't car repair and it wasn't going out of it.

Try hovering your mouse cursor over the car.

Yep, I can confirm this. Entering works fine when you do not hover your mouse over the vehicle and crashes immidietly when you hover over.

Entering car also crashes the game with a similar error
