WordPress childtheme not loading any CSS/SCSS

after you registered and activated child theme you should add wp_enqueue_style( 'child-style', get_stylesheet_directory_uri( ) . '/css/screen.css', array('parent-style', 'bigfoot-style', 'bigfoot-css'), wp_get_theme()->get('Version'));

in your childs theme functions , i assume by adding get_stylesheet_directory_uri( ) to your main theme ytou get wrong path ,
and there is a space in get_stylesheet_directory_uri( ) <=== please remove space from brackets.“`
