Did I blow my trans or my diff PLEASE HELP

Just bought a 2012 335i with 88k today and as I’m driving it back home I stop at a red light and did a very slight launch, I hit a small pothole and heard a loud pop and the car immediately went up in revs and heard metal breaking now the car won’t move at all. When I looked underneath I saw the drive shaft spinning when It was in drive and stopped when it was in park but no power to the wheels. What do you think I’m getting it looked at tmr but just want some opinions. My buddy happened to be recording so I have a video I can post as well.

You likely snapped an axle.
