Save corrupted steam user

I am a team player. this morning I woke up at 4:00 to bring my character from level 31 to 40 near the dlc that will have to come out, and suddenly the game crashed and returning to the selection of the character I saw that he was corrupt. after playing it 18 hours is not fair! and now ?

Did you have steam cloud saves enabled? If so, you might be able to roll back to the previous version. Same if you had Windows Backup enabled on your saves folder - you should be able to right-click and revert to an earlier version.

I tried many methods but not this one, I hope I can do it. thank you

I did it. but saving the corrupt character dates back to when it was corrupted. then an already corrupted save was saved to the cloud.
