Editor not working on homepage

The editing of the home page by Elementor is not working. According to my developer the error is in editor.min.js file Provided by Elementor. He thinks that this is the plugin’s bug and says I must speak to support?

He has updated all the plugins and everything else is working correctly its just the editing on the Home page.

Please can you advise how we can fix this? Do we need to buy a new lisence possibly? The old Pro version is installed and active now, but I’m not sure if features from this code working for this project.

PLease help!
