@burnout426 have the same problem i am on android and i still have all of bookmarks, how to sync them to server, pls help

So i reinstalled my windows. Casually downloaded opera gx, tried to log in and it said that to sync my bookmarks i need to write my secret word or smth, which i don't even remember having, so i just rebooted it and all my bookmarks got deleted from my opera acc, which i wasn't scared of bc i still have them all on my synced phone, but now i can't sync them to my pc from phone, they won't sync to opera acc, and i don't know how to do it now. Phone just won't sync but it says that everything is sync'd up.
