Elementor editor not loading

Hi,

We have an issue with the elementor editor not loading when this plugin is enabled.

I’ve tested with only the following plugins/themes enabled

Plugins:
Elementor V3.8.1
Elementor Pro V3.8.1

Themes:
Hello Elementor V2.6.1

There are no PHP errors, but the below console errors are logged when enabling this plugin and trying to load the editor.

Object { message: "JSON.parse: unexpected character at line 2 column 1 of the JSON data", code: "", data: [] }
source: https://mysite.com/wp-content/plugins/elementor/assets/js/web-cli.min.js?ver=3.7.6

SyntaxError: JSON.parse: unexpected character at line 2 column 1 of the JSON data
source: https://mysite.com/wp-content/plugins/elementor/assets/js/web-cli.min.js?ver=3.7.6

Here’s a screenshot of the console log https://snipboard.io/VlAnic.jpg

Can you please check and advise?

Many thanks.
