Here's my quicksave if anyone is interested. Just talk to the Twi'lek and ask for a practice or real race, and get a winning time.
Update: Happens with 2.1.0.0 nocd as well (as opposed to 2.2.0.0 Steam), and I get a bonus bug of being stuck in the air sometimes.
I did find something, however: it seems that I was using Atton to start the race instead of hte player character. When I used the PC instead, there was no crash. Could it be that simple? I know it at least makes a difference for the persuasion check to skip the entry fee.
