I am stuck at a checkpoint inside the security building at Wall Street (where you flip the switch to open the tunnel).

I died and respawned inside the trailer in a corner by the switch, but my avatar is stuck. I can turn, but I can't move at all, or even crouch. I have tried dislodging myself with grenades, and even looked for a no-clipping cheat code online to get me out of my position, but to no avail.

Help! I'd rather not have to replay the four hours I've already put into the game. Can you give me a way to dislodge or even jump to the next checkpoint to get me out of this situation? Thanks.
