I would not expect a page move (rename) to take > 48 hours. If I'm wrong, please correct me.

Trying to "Move" myself, it says
You do not have permission to move this page, for the following reason: This page is locked because the translatable page is currently being moved.
Translatable pages consisting of too many pages can no longer be moved through the web interface, because it is unreliably. Going forward, such pages can be only moved using a command line maintenance script, which for WMF wikis can be requested through Phabricator task for Wikimedia-Site-requests.
