Persona 5 [NPEB02436] freezing after being playable

Just remove the save data that's corrupt, you'll have to figure out which one it is, there are 16 slots on Persona 5.

You obviously can't know if the save will corrupt or not before it does. It can corrupt if your computer loses power, the OS or the application crash, etc.
The solution is keeping backups of your saves as with everything else.

I removed all of the save data and it still kept freezing. I also reinstalled both the emulator and the game and the problem still persists.
