Fatal Error with Elementor : undefined function get_current_screen()

Hi !

I'm facing a fatal error :

Fatal error: Uncaught Error: Call to undefined function get_current_screen() in .../wp-admin/includes/template.php:1379
Stack trace: 
#0 .../vendor/meta-box/meta-box/inc/fields/taxonomy.php(359): remove_meta_box('thematiquediv', NULL, 'side')

#5 .../vendor/meta-box/mb-frontend-submissio in .../wp-admin/includes/template.php on line 1379

The frontend shortcode is on a custom woocommerce endpoint.
Since the "My account" page has been modified with Elementor it generate this fatal error. Before it was working smoothly.

My code is in a plugin with metabox has a composer dependency.

I "fixed" it by adding a check before calling the shortcode but it's not pretty 😉 :

if (! function_exists('get_current_screen')) {
  function get_current_screen() {
    return null;
  }
}

Thanks in advanced for your time !
