Klarna Checkout hangs/freezes on payment with GP child theme active

Hi!

I have set up a staging environment for this new site to find out what is causing the payment process to freeze.
So I found out that something in my child theme seems to be the cause of the problem. When switching back to the parent GP theme, everything is working just fine.

What could be the cause of this behavior?

My functions.php contains the following:

<?php
/**
 * GeneratePress child theme functions and definitions.
 *
 * Add your custom PHP in this file.
 * Only edit this file if you have direct access to it on your server (to fix errors if they happen).
 */

 /*
*********************
* ACTIONS
*********************
*/

//  All included script files
function itc_included_files() {
  wp_enqueue_style('itc-main-styles', get_theme_file_uri('/build/assets/css/main.css'), array(), '1.0', 'all');
  wp_enqueue_style('itc-fontawesome', 'https://cdnjs.cloudflare.com/ajax/libs/font-awesome/6.1.1/css/all.min.css');
  wp_enqueue_script('itc-google-map', 'https://maps.googleapis.com/maps/api/js?key=the_api_key_hidden_right_here', array(), '1.0', false);
  wp_enqueue_script('itc-main-js', get_stylesheet_directory_uri() . '/build/assets/js/main.js', array('jquery'), '1.0', true);
}

add_action( 'wp_enqueue_scripts', 'itc_included_files' );

// Setting the Google Map API for ACF
function itc_acf_init() {
  acf_update_setting('google_api_key', 'the_api_key_hidden_right_here');
}
add_action('acf/init', 'itc_acf_init');

// Customize login screen - Make sure to separate this stylesheet from the main one in Codekit!

function itc_login_styles() {
    wp_enqueue_style( 'custom-login', get_stylesheet_directory_uri() . '/build/assets/css/itc-custom-login.css' );
}
add_action('login_enqueue_scripts', 'itc_login_styles');

// Customize Login Screen

add_filter('login_headerurl', 'itc_header_url');
function itc_header_url() {
  return esc_url(site_url('/'));
}

Thank you!!
