[נפתר] Deleting a language

Background of the issue:
I am working on a site under development and trying to delete a language in WPML. I deactivated the language, but there are still existing translations saved in the database. The system shows the number of media, pages, tours, courses, and navigation menus associated with the language.

Symptoms:
When I start the delete process, it takes a long time, stops, and I see the number of media slowly decreasing.

Questions:
Is there a way to properly delete a language in WPML?
Can I delete all the media associated with a language in some other way?
