Cannot edit Jeg Elementor Kit header/footer/404 pages

Hello

I am no longer can edit any of the Jeg Elementor Kit powered templates inlcuding header/footer/and 404 pages: https://take.ms/ZHsIZ

When click on any of the templates to edit Elementor Edit never completely loads and get stuck loading screen: https://take.ms/fjJGJ

If Elementor is in the Safe Mode, clicking Edit icon just redirects to /wp-admin/edit.php page

Disabling all plugins didn’t help either.

please help
