[PC] Car models not loading at all, most of the cars load as a black Ford (garage, in Game)

Issue:
car models are not loading at all, instead of the correct car model I am getting a black ford loaded all the time,
happens for more tha a half of the cars in tha game.

FM7 wwas played on XB1 before, then installed on PC over MS store,
all account sync is successfull,
this issue happens only on PC

all updates windows 10 , Nvidia , FM7 installed,
opened a bug for that
