Decks dissapearing after force syncing

So my syncing wasnt working and i read that i hve to do ”force syncing” so i did that and i lost 2 big decks how can i get them back??? thank you in advance

Anki creates local backups each time you quit the app.

You can find them like this:
FileSwitch ProfileOpen Backup...

Choose the most recent backup file where you still had your decks and restore it.

(Don’t worry if you don’t get the decks back on the first try, you can repeat that process until you find the right backup.)
