After killing every enemy in the room, the player character was teleported back to the middle of the room, where the player character was no able to move, to shoot, to reload or to perform any other action except rotating in the direction of the mouse position.
When entering the pause menu, buttons to click on did not appeare and therefore i could not leave the round.
There was no object in the middle of the map where the player character could have been stuck.
Unfortunately i dont remember the room. I only remember that it was in an anger room.
