Digimon World 3 crash Pcsx rearmed

Hi, i am new to retroarch (ios) and been playing digimon world 3 pcsx rearmed.

It run so smooth, but suddenly the game hang.

• audio is running well
• the tiles behind is running
• the digimon is not moving
• i can’t do anythinf

I cannot undo the save state because i already closed the game.

Is there anything I can do to fix this? Some thing like skipping some frame? Thanks!
