Strange, I am sure I was on the latest version, but today I couldn't replicate that dialogue break.
But, I found a spot without any collision, it's a window near the crate.
I found a new way to hard-lock the game, if you enter the pause screen in any dialogue, you lock any interaction and you can't exit.
I checked "new game" mechanic, it saves a lot of data of your previous playthrough, but saving - buying stuff/hurting yourself - loading different save, looks stable with no inventory changes or energy difference.
Bonus, if you run vault into the bed, you can get easily stuck and receive fall damage. :)
