Fix Elementor Editor Loading Issue and fix Security Ninja plugin issue

My Elementor page editor refuses to load when i try to edit wordpress pages. I have already ruled out the usual suspects: all other plugins are deactivated, I even switched to a default WordPress theme, and there are no visible PHP or console errors. Yet the editor still sits at the loading screen (screenshot for reference: https://www.awesomescreenshot.com/image/58632418?key=9cde2e344ede12ead1362ecf775dbd52).

I need someone who can quickly trace what Elementor is hanging on, apply the necessary fix, and leave the editor opening normally every time—no work-arounds, no hidden side effects. Please be comfortable digging into WordPress core files, Elementor settings, server-side configuration, and database entries if required.

Deliverables:
• Elementor editor loads and functions on all pages
• A short note summarising the root cause and the steps you took to resolve it
• Any permanent code changes documented in a child theme or a snippet so future updates stay safe

and also need assistance to resolve the below plugin error:
