My son's Pokemon Ultra Sun save file appears corrupted. Is there anything I can do?

[ElectricKaibutsu]

While he was playing Ultra Sun, he said something appeared on the bottom screen and now the game starts back at the beginning. I'm assuming his save got corrupted.

I do have CFW installed but unfortunately have no backups of the save file. I looked at the game in PKSM but it's showing 0 pokemon.

Is there anything I can try to recover his file?

 

Edit: I believe this is the save file. I don't know if it's corrupted or if it's been overwritten with a new game save somehow.
