bug with nuka wold arena (Fallout 4)

steam license.
I ran into a bug, getting into the nyuki arena, where you have to kill the boss in power armor - my whole arena is littered with huge bottles of nyuki that I can go through, but I can't see nichrome because I suspect there are more than a dozen of them there, that is, clean I don't see space at all, I restored files, lowered the video to a minimum with a minimum of drawing objects - it does not help.
I can of course give screenshots, but you will not see anything other than these walls, who came across? how to solve?
