Impossible de démarrer Dropbox

Depuis la mise à jour de mon Macbook Pro 15" mi 2019 sous MacOS Monterey, il m'est impossible de démarrer Dropbox.

Le message me signale qu'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.

On me demande de transmettre à l'assistance Dropbox ce rapport d'erreur :
