Error during trophy registration. The game will now be terminated

Hi everyone.
I'm currently playing Dragon's Crown on the emulator and i had no problem till now. When i try to start the game, everything is loaded, but then this happens: https://ibb.co/BwLMzcH and i can't play anymore. I don't remember doing anything unusual last time i played, i don't know what to do. Even if i'd start all again, what if this happens again? Help please, thank you.
