Lost project

Hey there, not too long ago i had made a map that took about month to make and finished it, i published a private version but don’t remember if i had revision control on, which it should be automatically on. And then my virus got infected with viruses so i had to format it forgetting that i had a whole map made because i was in a panic, and formatted the pc. I don’t remember the name of the project either, so now i log into UEFN and cant find it anywhere, is there any way i can get the map back?
