SendMail activity is not sending email with attachments. Keeps in drafts without sending

How do I fix this error? My SendEmail activity was working earlier, but now it is not. I don’t understand what went wrong. I think it has to do with the attachments collection, but I don’t know what changed. When I take out the attachments, it sends normally, but when I add the collection, the SendEmail activity creates the email but saves it in Draft without sending. How do I fix?
