I had the same issue. Specifically, this is was happening in the elevator, at the end of the running section that follows the cutscene mentioned in the original post.
Update: it happened two times in a row and after coming here to look for information and making the comments above, I booted the game up again and was able to get past this part. The only difference was this time, following getting knocked down and regaining control in the elevator, i did not move my character at all or read the character description that appears until the elevator made it all the way up and the doors opened (previously I'd both moved around and read the character description both of the times I encountered the bug).
