Broadcast Premium endless loop in sync

I’m opening a new topic, because it’s a different issue.

A custom post type element, when changed and broadcasted to another site stays in the queue forever. In the Broadcast queue view the element switches from “processing queue” to “Zero of 1 items are ready”

Broadcast plugin version 48.15?and Broadcast Premium Pack 48.14.

debug.log: I dont know if the first messages can give a clue about the problem, but they always appear above the broadcast error message.
