Don't bother it looks like it's a rather rare bug, also my solution is not permanent, after I completed the quest I went through the concourse about 8-10 times no problem and then the game crashed again, I had a quick save just outside the doors and after reload it was fine to enter. Its just strange, stressful and apparently not to easy to repeat.

I had the same bug, I used tai before entering the concourse for the first time then got the body and all was wel after that, no more crashes when entering.
