[Resolved] Automatic translation

Background of the issue:
I have set up automatic translation on my site hidden link using WPML.

Symptoms:
The process shows 'Updating affected posts' for over a week and remains at 0, never progressing further.

Questions:
Why is the automatic translation stuck on 'Updating affected posts'?
How can I resolve the issue of the translation process not progressing?

I already did these:
Clear WPML cache, Fix post type assignment, and Reset professional translation status
