After latest update, something broke with automatically creating accounts

Hey!
After the latest update something broke with my script.
What has changed here? ??

add_action(‘woocommerce_thankyou’, ‘wc_register_new_customers’, 10, 1);
function wc_register_new_customers( $order_id ) {
if(is_user_logged_in()) return; // Only for unlogged users

// Get an instance of the WC_Order object
$order = wc_get_order($order_id);

// Get the customer billing email from the order
$billing_email = $order->get_billing_email();

// check if there are any users with the billing email as user or email
$email = email_exists( $billing_email );
$user = username_exists( $billing_email );

// if the UID is null, then it’s a guest checkout
if ( $user == false && $email == false ) {

$random_password = wp_generate_password();

// Create new user with email as username & newly created pw
$user_id = wp_create_user( $billing_email, $random_password, $billing_email );

//send PW
$wc = new WC_Emails();
$wc->customer_new_account($user_id);

// WC guest customer identification
update_user_meta( $user_id, ‘guest’, ‘yes’ );

//user’s billing data
