PHP Fatal error: Call to undefined function get_current_screen

The previous version and the new one generate a fatal error when visiting the admin url from within private browsing: https://www.domain.com/wp-admin

An error page is presented in the frontend and the debug.log says:

[22-Mar-2022 10:08:41 UTC] PHP Fatal error:  Uncaught Error: Call to undefined function get_current_screen() in \wp-includes\script-loader.php:2356

The workaround that’s working for me is:
\plugins\hide-login-page\libs\factory\templates\includes\class-helpers.php line ~77

if( $wp_query && is_object($wp_query) ) {
	$wp_query->set_404();
	#alx359-->
	#get_template_part(404);
	header('Location: /');
	die();
	#<--alx359
} else {
	global $pagenow;

HTH.
Thanks.
