Cards disapearing from decks

Hello,
I just downloaded the new anki version for Mac OS : 2.1.33 and since then when i create a card inside a deck, the card vanishes from the deck and it goes nowhere. I have to go to browse -> Filter -> Added today to find the card wich is in no deck.
Please help me i can’t create cards anymore and study it because of this issue.
I tried to check database and other things but nothing works.
