First, make sure your username in game is shown correctly as your steam profile, and not your computers name. If its not matching your steam name, restart Steam and log back in.
If that doesnt work, go to your D:\Steam\steamapps\common\Deep Rock Galactic\FSD\Saved\SaveGames folder, find the most recent Backup save and change its name to player.sav replacing the original one.
Also try the new in game recovery option, its in the options and account, where you can choose older saves
