Some cars make my game crash in Free Play

So, yeah, the title is pretty self-explanatory. Whenever I want to use the Alfa 8C 2300 (the oldie from this month’s DLC) or the Porsche F1 car in Free Play, my game just crash. Won’t load the track as I’m stuck at the track selection screen in the beginning.
Tried to trick the game by changing the car in the pre-race lobby, but all the Drivatars disappear and when I wanna start it gets stuck on the black loading screen and then… Nothing. What gives ?
