I’ve lost all my data

As the title says, I’ve randomly lost all my data.

I put around 126 hours into this game on PS5, had platinum, and was sitting at 242/244 trophies only missing two adventure trophies. I had also 100% completed all of the free DLC, just like I did with the rest of the game including the paid dlcs.

But when I logged back in after a while, everything was gone. I’m missing a character, I have 0 gold, and it’s like my entire save has been reset. All the characters from the dlc and item power-ups. I bought and fully completed every item, every character is just gone. Now obvious I still have the dlc but you get it everything I’ve unlocked playing the DLC+ base game gone.

This is honestly really concerning. Has anyone else experienced something like this or know what might have caused it?
