[PLZA] Find the flag that disables the camera mode

[Alegria]

So I have a problem that of course the Pokémon support will not help me with (they say contact nintendo and nintendo says contact pokémon)
I'm currently in the DLC and I noticed I can't trigger the camera mode with the minus button, or with the ZA royale profile (the option to change the picture doesn't even appear in the screen). Camera mode with the Y button is possible when sitting at a bench or a cafe table.
It is not a mod, update or hardware issue. The minus button isn't faulty, I can still change my clothes from the menu, and the memory isn't faulty as the bench/cafe pictures and the screenshots from the switch's screenshot button work perfectly. Also, I have a couple archive save files that have it still working, and any new game save file also can.

My theory is that at some point I've been in an event or a place where the game disables the camera mode, and the game forgot to turn it back on when I left. I noticed it first when I went to my first mission with my rival and Korrina in hyperspace, but thought that dimension was just not allowing pictures. I know I have been able to take pictures the day before when I caught Mewtwo so whatever happened was in the post game. My hope is that finding the flag would allow me to fix it manually using pkhex.

I can't remember when the game could have disabled the camera mode though. I remember noticing it in Scarlet/Violet because I really wanted to take a picture in the room where you fight the Professor and it's disabled (in the place where you find Terapagos as well), but I guess it doesn't help as it's probably a whole different flag.

Did you cheat to unlock Mewtwo, or use any cheats/save edits on the file previously?

I did, but I was able to take pictures after getting Mewtwo and Diancie, it happened afterwards. I literally have a save file from after I caught both that still has the camera mode, and I didn't play with file editor afterwards.
