Woocommerce Cart - Sort by Category - wordpress

Question

I need help. I want to sort prodyct in my cart page by category like this:
Category1
Product1
Product2
Product3
Category2
Product1
Product2
Product3
Category3
Product1
Product2
Product3
I found this code but it is working strange. For some products it is sorting OK, but for other - no. Could you help me?
add_action( 'woocommerce_cart_loaded_from_session', function() {
global $woocommerce;
$products_in_cart = array();
foreach ( $woocommerce->cart->cart_contents as $key => $item ) {
$terms = wp_get_post_terms($item['data']->id, 'product_cat' );
$products_in_cart[ $key ] = $terms[0]->name;
}
ksort( $products_in_cart );
$cart_contents = array();
foreach ( $products_in_cart as $cart_key => $product_title ) {
$cart_contents[ $cart_key ] = $woocommerce->cart->cart_contents[ $cart_key ];
}
$woocommerce->cart->cart_contents = $cart_contents;
}, 100 );```

You also need to set new cart session and you can also utilize $cart property passed into action:
( Although I have not tested this idea please try )
add_action( 'woocommerce_cart_loaded_from_session', function($cart) {
$products_in_cart = array();
foreach ( $cart->get_cart() as $key => $item ) {
$terms = wp_get_post_terms($item['data']->get_id(), 'product_cat' );
$products_in_cart[ $key ] = $terms[0]->name;
}
asort( $products_in_cart );
$cart_contents = array();
foreach ( $products_in_cart as $cart_key => $product_title ) {
$cart_contents[ $cart_key ] = $cart->cart_contents[ $cart_key ];
}
$cart->set_cart_contents($cart_contents);
$cart->set_session();
}, 100, 1 );
