Delay in campaign actions and conditions

Your software
My Mautic version is: v5.1.1
My PHP version is: 8.1.29
My Database type and version is:10.5.25-MariaDB-ubu2004

Your problem
My problem is: If I use the delay function for sending an email, for example, the emails are placed in the queue (see upcoming emails in the dashboard). When the sending time is reached, they disappear from the queue and are shown as ‘pending actiong’ in the email action. This problem occurs regardless of how the delay is created (wait time, wait until a point in time)

These errors are showing in the log: log is empty

Steps I have tried to fix the problem: tried different waiting styles, offer always a way to push the contact out of the campaign.

Hello, what SMTP do you use and how do your queue settings / email sending cron look like?

smtp amazon aws
emails are sent via doctrine messenger queue, consumer is running, emails are sent, queue is empty
