After upgrading to 12.7.6 random emails are stuck

Since upgrading to 12.7.6 about 10% of our emails are getting stuck in the "delayed action" table. Clearing it out does nothing, changing the email settings do nothing. Since support isn't answering emails or the phone I figured I'd try here. Has anyone else seen anything similar? We get the below log entries every time it happens.
