Woocommerce minimum order for certain product categories and exclude categories

I have a minimum order amount of 3 products from Chilled category.

If there are no Chilled category products in the cart and any combination of other product categories (Bundle, Ambient, Gifts) in the cart, the customer should be able to checkout.

If there is less than 3 Chilled category products in the cart but there is also a Bundle category product in the cart, the customer should still be able to checkout.

My wc_add_notice error is counting the Chilled logic correctly, but it is displaying even when there are no items from the Chilled category in the cart.

Please can someone help where I am going wrong?

// Set minimum quantity per product before checking out
add_action( 'woocommerce_check_cart_items', 'chilled_set_min_total' );
    function chilled_set_min_total() {
        // Only run in the Cart or Checkout pages
        if( is_cart() || is_checkout() ) {

            global $woocommerce, $product;
            $i=0;
          
            // Set minimum product cart total
            //And initialise product catergory counters
            $minimum_chilled = 3;
            $total_chilled = 0;
            $cat_in_cart = false;
            
            //check if chilled product in cart. If exists add to quantity
            foreach ( $woocommerce->cart->cart_contents as $product ) :
                if ( has_term( 'chilled', 'product_cat', $product['product_id'] ) ) {
                   $total_chilled += $product['quantity'];
                }
                if ( has_term( 'bundles', 'product_cat', $cart_item['product_id'] ) ) {
                    $cat_in_cart = true;
                break;
             }
            endforeach;
          //if chilled items is less than minimum display error
            if ($total_chilled < $minimum_chilled) {
                wc_add_notice( sprintf( '<strong>A Minimum of %s products are required from The CHILLED category before checking out.</strong>'
                . '<br />Current number of Chilled items in the cart: %s.',
                    $minimum_chilled,
                    $total_chilled ),
                'error' );
            }
        }
    }

Your problem in this line

if ($total_chilled < $minimum_chilled) {

if we have no chilled, so $total_chilled dont change and = 0

So we have 0 < 3 and its always = true

To solve this problem you need to add one more check

  //Check if there are any products from this category in the cart
  if ($total_chilled > 0) {
  
  //if chilled items is less than minimum display error
    if ($total_chilled < $minimum_chilled) {
        wc_add_notice( sprintf( '<strong>A Minimum of %s products are required from The CHILLED category before checking out.</strong>'
        . '<br />Current number of Chilled items in the cart: %s.',
            $minimum_chilled,
            $total_chilled ),
        'error' );
    }
    
    }

Update, if you need to disable checkout button add

remove_action( 'woocommerce_proceed_to_checkout', 'woocommerce_button_proceed_to_checkout', 20 );

  //Check if there are any products from this category in the cart
  if ($total_chilled > 0) {
  
  //if chilled items is less than minimum display error
    if ($total_chilled < $minimum_chilled) {
        wc_add_notice( sprintf( '<strong>A Minimum of %s products are required from The CHILLED category before checking out.</strong>'
        . '<br />Current number of Chilled items in the cart: %s.',
            $minimum_chilled,
            $total_chilled ),
        'error' );

    remove_action( 'woocommerce_proceed_to_checkout', 'woocommerce_button_proceed_to_checkout', 20 );

    }
    
    }
