Impossible Mode Chapter 12 Server Room Battery Missing/Can’t Progress

Hi, so I have a similar issue regarding the “restore power to shutter” objective. I’m in chapter 12 of impossible mode and the battery is not in the room with the stasis recharge/server room. I stomped the boxes, fought two infectors and somehow a necromorph spawned even though I already had prevented that from happening. Whenever I see a room full of dead bodies I stomp them so that they have no limbs. With that in mind I did that and defeated the enemies and saved the game. I went to retrieve the battery,  once I had returned it was no longer there. I’ve already saved as clearly impossible mode has one slot to save and now I’m stuck unable to progress because the door is inaccessible to bring the marker in to continue the game. I am running the most current version for ps5 digital deluxe edition have completed the game several times on the hard difficulty and never had this experience until now. I nexperienced more bugs with this  version (1.000.006) which mostly deals with maneuvering items and items staying in the correct plane. Such as enemies disappearing through the walls). I have included as much info that is relevant. Please help me finish this game. I’ve made it this far while playing with a dislocated/recent surgery to my thumb/wrist so simply not being able to complete this is really frustrating.
