Game breaking glitch? Need help (3rd night, FishTankRoom)

Playing thro it for my first time, was really enjoying it although 3rd night has been pretty bleak
Anyways just got thro the FishTankRoom again normally, looted the shrine, came back and saved the game
and now, I'm straight up stucked
Like quite literally this door doesn't open in any way
No text or message about it, I've sit here with fast forward grinding random spawning ghost encounters praying it could have something to do with this glitch,
Reset the game, the emulator, walked around the entire area multiple times
Have tried from opening from different angles, walking on Finder mode
And a whole bunch of shit just trying to make it work but it simply doesn't
This might actually just be the first time I've genuinely had a hardlock glitch ever which is just a shame considering I couldn't find anything about this anywhere in the internet atleast so far
Not sure if I should try and fuck around with a debug menu
I'm afraid of fucking up something
