Have them check the brake light switch.
When you normaly press on the brake, that switch engages the solenoid to release park.
During your encounter spinning into the curb ( and many other ‘‘oh crap’’ driving scenarios ), it’s normal human nature to slam that brake with all one’s might and THAT is beyond normal for the pedal and switch.
You pushed the switch out of adjustment, broke the switch, or bent the lever on the pedal that pushes it.
