I'm going to try to find out what happened to cause the box to get stuck, I can't find what is causing this, this doesn't happen to me.
My guess is i got in the box as i was being killed. Normally he pulls you out of the box and then kills you but i died as i was getting so i never got out.
Did you press E to interact with the box at the same moment he killed you? So that must be it. Thank you, I'll fix it.
