Slick slider is not working on one of the wordpress pages. What to do?

Question

Slider

I pulled the site on WP, connected all the scripts and styles.
On the second page of the site, this is:

On the other page, 2 sliders behave naturally.
They eat code from two different JS files with scripts:
Working ( ind-scripts.js ):

// Slick Slider
$('.it-idv-slider').slick({
  //arrows: true,
  //autoplay: true,
  autoplaySpeed: 3500
});
$('.it-idv-slider-comment').slick({
  arrows: true,
  autoplay: true,
  autoplaySpeed: 3500
});

Not working ( balloons-scripts.js ):

$('.balloons-slider').slick({
  arrows: true,
  autoplay: true,
  autoplaySpeed: 3500
});

$('.balloons-can__slider-m').slick({
      arrows: true
    });

but most likely it's not the jaes files.
And without WP on the locale, everything works fine, it feels like
this particular page spits styles and code.
Here is for every functions.php:

add_action( 'wp_enqueue_scripts', 'colorball_styles' );
add_action( 'wp_footer', 'jquery_lib' );
function jquery_lib(){
  wp_deregister_script( 'jquery-core' );
  wp_register_script ( 'jquery-core', get_template_directory_uri() . '/assets/js/jquery-3.4.1.min.js' );
  wp_enqueue_script( 'jquery' );
  wp_enqueue_script( 'jquery.event.move', get_template_directory_uri() . '/assets/js/jquery.event.move.js', array('jquery'), null, true );
  wp_enqueue_script( 'jquery.twentytwenty', get_template_directory_uri() . '/assets/js/jquery.twentytwenty.js', array('jquery'), null, true );
  wp_enqueue_script( 'jquery.simple-dtpicker', get_template_directory_uri() . '/assets/js/jquery.simple-dtpicker.js', array('jquery'), null, true );
  wp_enqueue_script( 'wow', '//cdnjs.cloudflare.com/ajax/libs/wow/0.1.12/wow.min.js', array('jquery'), null, true );
  wp_enqueue_script( 'slick', '//cdn.jsdelivr.net/npm/[email protected]/slick/slick.min.js', array('jquery'), null, true );
  wp_enqueue_script( 'scripts', get_template_directory_uri() . '/assets/js/scripts.js', array('jquery'), null, true );
  wp_enqueue_script( 'ind-scripts', get_template_directory_uri() . '/assets/js/ind-scripts.js', array('jquery'), null, true );
  wp_enqueue_script( 'balloons-scripts', get_template_directory_uri() . '/assets/js/balloons-scripts.js', array('jquery'), null, true );
  wp_enqueue_script( 'smile-bar', get_template_directory_uri() . '/assets/js/smile-bar.js', array('jquery'), null, true );
  wp_enqueue_script( 'lightzoom', get_template_directory_uri() . '/assets/js/lightzoom.js', array('jquery'), null, true );
}
function colorball_styles() {
  wp_enqueue_style( 'style', get_stylesheet_uri() );
  wp_enqueue_style( 'normalize', get_template_directory_uri() . '/assets/css/normalize.css');
  wp_enqueue_style( 'twentytwenty', get_template_directory_uri() . '/assets/css/twentytwenty.css');
  wp_enqueue_style( 'animate.min', get_template_directory_uri() . '/assets/css/animate.min.css');
  wp_enqueue_style( 'jquery.simple-dtpicker', get_template_directory_uri() . '/assets/css/jquery.simple-dtpicker.css');
  wp_enqueue_style( 'slick-theme', get_template_directory_uri() . '/assets/css/slick-theme.css');
  wp_enqueue_style( 'slick', '//cdn.jsdelivr.net/npm/[email protected]/slick/slick.css');
  wp_enqueue_style( 'smile-bar', get_template_directory_uri() . '/assets/css/smile-bar.css');
  wp_enqueue_style( 'lightzoom', get_template_directory_uri() . '/assets/css/lightzoom.css');
}

Answer 1

A script was connected that did not work and did not allow the slick to work.
If someone has a similar, just connect everything in turn and check.
