wp_editor in widget breaks after save (no buttons and visible tab damaged)

My objective is to get wp_editor working in a easy widget which the admin can use so as to add textual content content material on an admin choices web page.

Right here we go in wp-admin/widgets.php all the things appears sooo good proper.

After we attempt to save… Oh no….. Buttons are gone and the Visible tab now not works

After I have a look at the HTML it seems as if after updating TinyMCE simply decides it does not must load any buttons… Any concepts?

Edit: here is the supply for the plugin I wrote that is throwing this error

add_action('widgets_init', 'string_example_name_init');

operate string_example_name_init()

    register_widget('string_example_name');

            'description' => 'String Instance Title'
        );

        mother or father::__construct('string_example_name', 'String Instance Title', $widget_details);
    }
