I managed to replicate the issue, here is the deal...
So it appears that I had previously entered the elevator menu, and then proceeded to exit the menu without clicking on any buttons, this prompted the door to lock behind me, and since my character was right next to the door, I was able to "see" through it, giving the illusion of transparency. I have killed my character in an attempt to retrieve the loot, but to no avail. I can grab the spare ammunition from the door, but I am unable to grab my actual gear...
BUT
There may be a solution, which would simply be someone coming to the BoS headquarters and unlocking the door, hopefully freeing my character from his eternal limbo.
That is what I have thus far, if you still need an image please let me know.
