Hi mate, send me admin login details via email for that site and I'll see what's going on.

Thanks for the fast response. I've sent the login details via your contact form.

To re-create the issue. After logging in, in the left sidebar go to Oxygen > Templates > Edit with Oxygen, and the Builder Editor loads with a cog icon in the center of the screen. With your plugin active, the loading screen remains is stuck. With the plugin inactive, the Builder Editor loads correctly.

For anyone else that comes across this thread, the solution is to add a custom snippet with the following code:

add_action('init', 'custom_disable_free_download_scripts_if_editor');
function custom_disable_free_download_scripts_if_editor()
{
	if (!empty($_GET['ct_builder'])) remove_action('wp_enqueue_scripts', 'somdn_load_scripts');
}

Awesome! Thanks for the rapid response and solution 👏
