I was one of those that suffered from this problem and found my issue was with the screen refresh rate.
By default my screen refresh rates are, for example:
1920i X 1080 - 30Hz
1920p X 1080 - 60Hz
Neither of which are available for selection in the Video Options setup of this game.
Once I changed my refresh rate to match the selections available from the game:
1920i X 1080 - 23Hz
1920p X 1080 - 59Hz
My lockup problems on track load went away.
So make sure your screen refresh rate for the available selections matches one of those choices.
