Game-breaking bug – dungeon doors stay locked after clearing enemies

[vagrant wave]

Hello Support Team,
I would like to report a game-breaking bug I encountered in Cult of the Lamb.
As shown in the attached screenshot, all enemies in the dungeon room are defeated, but the doors remain closed and I am unable to continue. No new enemies spawn, and the room does not complete properly.
The only available action is holding R2 to return to the cult. Nothing else works, which forces me to abandon the run.
This issue has already happened to me in two different dungeons in the Woolhaven area, so it seems to be repeatable.
Additional details:
Platform: PlayStation
Mode: Co-op
Location: Woolhaven dungeons
Result: Progress blocked, run must be abandoned
Please let me know if you need any additional information.
Thank you for your help.
Kind regards,
Miky

I would like to add more information about this issue.
The same bug also happened in a normal (non-DLC) dungeon.
In most cases, it seems to occur during fights against infected / Damned followers that appear as enemies in dungeons.
Specifically, this happens with a follower that I used very frequently to generate Sin at the Drum.
During the dungeon fight, the Damned follower enemy fell into the ground / disappeared, but the game still treated it as alive. As a result, the room never completed and the doors remained locked permanently.
This suggests the issue may be related to the Damned follower enemy despawning or not being properly cleared.
I hope this helps identify the cause of the bug. Thank you.

if you dont kill the mouth trap monster it sometimes fixes it only 1 of them its how i got past

I wanted to add that this bug also happens in dungeons where there are no Mouth Trap monsters.
So the workaround with not killing the Mouth Trap doesn’t help in my case.
It seems to be a general softlock issue, because now it can happen in any dungeon.
