Weapons hang in the air (Alien: Isolation)

When re-entering the cleared location, I found that all the revolvers of the killed people were hanging in the air half a meter above the floor. Not only can they be neither taken nor defused, but they also levitate. Is there anything you can do about this? It seems like a trifle, but it terribly interferes with immersion in the game. Everything that happens is already perceived as "South Park" of some kind. I don't care that a stranger is spinning and attacking somewhere nearby, I walk around these stupid revolvers. And I walk right through them. It seems that all patches in Steam should be installed automatically?
I'll try to google the problem, but if anyone knows where to tweak something in the game files, I would be grateful!
