Hello,
If you want to get all the decks back, do this:
Please try resetting your local changes. To do this:
Go to browse in your Anki → at the top click on ankihub addon tab → press reset all local changes
This will restore everything to what AnkiHub has unless you have specifically protected those fields
If your AnKing deck is showing 0 cards, please see this: Why does my AnKing Step Deck have 0 cards?
If this does not solve your issue, please take a screenshot of your Anki so we can further diagnose your issue
