Impossible d'ouvrir Dropbox

Bonjour, 

Après avoir effectué la dernière mise à jour sur mon Mac (macOS Monterey Version 12.0.1), je n'arrive plus à ouvrir l'application Dropbox. Un message d'erreur apparaît me disant : "Impossible d'ouvrir Dropbox. Une erreur d'autorisation est généralement à l'origine de ce problème. Une erreur peut aussi se produire si votre dossier d'utilisateur est stocké sur un partage réseau. Pour en savoir plus, cliquez sur le bouton d'aide ci-dessous. Veuillez contacter l'assistance Dropbox et indiquer les informations suivantes pour obtenir de l'aide :"

Ensuite lorsque je clique, ce contenu s'affiche :
