How to disable this WP script, and where does it come from?

Question

WordPress

Good day.
Comrades tell me. where does this script come from? and how to turn it off??? I didn’t install any plugins, but it heavily loads the site loading.


Function.php too

/* =====================CSS========================= --> */
function style_theme()
{
  // подключаем css стили 
  wp_enqueue_style('swiperBundle.min', get_template_directory_uri() . '/source/css/swiper-bundle.min.css');
  wp_enqueue_style('style', get_template_directory_uri() . '/source/css/style.css');
  wp_enqueue_style('restyle', get_template_directory_uri() . '/source/css/restyle.css');
}
function user_css()
{
  //Пользовательский css 
  wp_enqueue_style('style', get_template_directory_uri() . '/style.css');
}
add_action('wp_enqueue_scripts', 'user_css');

  add_theme_support('title-tag');
  add_theme_support('post-thumbnails');
  add_theme_support('woocommerce'); 

  remove_action('wp_head','wp_generator');
  remove_action('wp_head','wlwmanifest_link');
  remove_action('wp_head','rsd_link');
  remove_action('wp_head','rest_output_link_wp_head',10);
  remove_action('wp_head','wp_oembed_add_discovery_links');
  remove_action('wp_head','wp_shortlink_wp_head', 10, 0);
  remove_action('wp_head', 'feed_links_extra', 3);
  remove_action('welcome_panel', 'wp_welcome_panel');
  remove_action('admin_color_scheme_picker', 'admin_color_scheme_picker');
  add_filter( 'emoji_svg_url', '__return_false' );

Answer 1

demolished function, header & footer but for some reason the view is pulled up ... it has nowhere to take it from.. explain.
Solution, connected the script as expected with array (), NUll, true
However, the question is open. Even if you demolish the plugins folder and the entire function.php header and footer, then you will see the formation of such a code
