Elementor Not Loading Edit Page

Hello,

For a few weeks now, I’ve been having trouble getting the Elementor page builder to load on previously built pages. When I go to edit a page and click “Edit with Elementor”, it goes to the loading screen with the “E” logo, the green progress bar at the top loads up and then disappears, and then the screen just sits there and nothing happens.

When I start up a new page with Elementor, the editor loads up just fine.

Sometimes when I roll back to the previous version of Elementor it works (on many occasions it doesn’t), but it also introduces other issues and one time I almost destroyed my content by doing that so I’m not sure that it is a good fix.

Before this issue started, I went months without any issues and I built many pages using Elementor. Now, I can’t edit my existing pages, so any help with this issue would be really appreciated!
