Outlook refuses to send attached pieces when sending an email (new with macOS Sequoia 15.4.1)

It works a couple of times and then… suddenly, Outlook (16.96.2) just doesn't accept to send attachment files (even very light), even if, as it says, I delete the attachment file, close the software and open it again.
Mac OS sequoia 15.4.1

Thank you for your help

    Hi @Anne-Claude Paré

    According to my research, it is related to a known issue with Outlook for Mac.

    You can refer to this Unable to add files as an attachment to emails in Outlook for Mac
