AnkiSync problem

Erreur
Une erreur est survenue. Veuillez démarrer Anki en maintenant la touche majuscule enfoncée, ce qui désactivera temporairement les greffons que vous avez installés.
Si le problème ne survient que lorsque les greffons sont activés, veuillez utiliser le menu Outils > Greffons afin de désactiver certains greffons. Redémarrez Anki jusqu’à ce que vous découvriez le greffon qui cause le problème.
Une fois ce greffon découvert, merci de signaler le problème sur le site de support du greffon.
