Workaround

Please, be sure to make a full backup of your site before proceeding.

1. Open your functions.php theme file.
2. Add the following snippet:

   if (defined('DOING_AJAX') && DOING_AJAX && !empty($_POST['action']) && 'menu-get-metabox' === $_POST['action']) {
   	add_action('pre_get_posts', function($query){
   		 $query->set('suppress_filters', false);
   	});
   }
