Pokemon Ultra Sun saves corrupted

[sweler18]

Hi everyone! I'm opening a topic here because maybe I was in the wrong section.
 

Today when I opened Pokémon Ultra Sun told me that the save was corrupt. I tried with Partial Savefile fix tool and it tells me that the size is correct. But pkhex doesn't open it either, it gives me invalid save file loaded. Can you give me a hand? I don't want to start everything again. I also tried to take a look at how save games work, and how to read them with a hex editor. I was told that maybe my file can be compared with a valid one but apart from that file I don't have any others.

 

Thank's
