Audi A8 Boost Bug

We just started a B class boost. Got to the boost, lockpicked it at the resort on great ocean highway. Pulled out of the parking lot, and it immediately gave a notifcation on the phone saying "you've failed me, get lost" and the car instantly disabled? I'm kind of unsure what happened but i can only assume its a bug, It cost 150 SVC. It was an Audi A8

Step One : Accept boost and lockpick it
Step Two : Start driving

Expected behaviour : Be able to start driving and hacking as usual
Actual behaviour : Car instantly disabled less than 50ft driving
