Installing a Child Theme & editting the style.css

Hi,

I am trying to install the child theme and edit the style.css file. I left the functions.php file as default and the stylesheet is not loading as should be. It's taking quite a long time for the page to load, which might be because of some overriding issue. Can you help me sort it plz?

The code is here:

Functions.php File (Child Theme)

<?php
/**
 * Betheme Child Theme
 *
 * @package Betheme Child Theme
 * @author Muffin group
 * @link https://muffingroup.com
 */

/**
 * Child Theme constants
 * You can change below constants
 */

// white label

define('WHITE_LABEL', false);

/**
 * Enqueue Styles
 */

function mfnch_enqueue_styles()
{
    // enqueue the parent stylesheet
    // however we do not need this if it is empty
    // wp_enqueue_style('parent-style', get_template_directory_uri() .'/style.css');

    // enqueue the parent RTL stylesheet

    if (is_rtl()) {
        wp_enqueue_style('mfn-rtl', get_template_directory_uri() . '/rtl.css');
    }

    // enqueue the child stylesheet

    // wp_dequeue_style('style');
    wp_enqueue_style('style', get_stylesheet_directory_uri() .'/style.css');
}
add_action('wp_enqueue_scripts', 'mfnch_enqueue_styles', 101);

/**
 * Load Textdomain
 */

function mfnch_textdomain()
{
    load_child_theme_textdomain('betheme', get_stylesheet_directory() . '/languages');
    load_child_theme_textdomain('mfn-opts', get_stylesheet_directory() . '/languages');
}
add_action('after_setup_theme', 'mfnch_textdomain');

--------------------------------------------------

The style.css is pretty much empty, except for the initial description.
