Blank Anki Deck

Hello, for some unknown reason my anki deck is appearing blank. I normally have all my decks which have been carefully organized on the main page. If i click of Browse tab I can see all my cards but they seem to have disappeared from the main deck. I recently saw an update for the hierarchical tag which I updated but i think this happened just before i updated the add-on can anyone help please me?

To start with turn off all plugins and also update your Anki.


Thank you so much the problem has now been fixed I updated my mac and updated Anki.
