Hours of progress lost

is there anyway to get it back?

Depends on how long it’s been since your save file got corrupted (I’m assuming that’s what’s happened from your question). You can try deleting local game save data then launching the game to re-sync the cloud versions. If the corrupted file didn’t get sync’d up (ie it’s reasonably soon since the event and you haven’t done anything that would force a sync) you might be lucky.
