deleted map after reseting pc/deleteding uefn

This is the third time this has happened—I deleted UEFN after resetting my PC, and now when I open my map, it’s just a blank template. How can I restore my map to how it was when I published it? Every time I ask this, my support tickets get closed after a month with no response.

Map code 8908-5694-2278 it was finished now its just the green default template it was when i first made the project

and i dont have onedrive enabled
