I have also faced same issue. And Below codes solve my issue.
Please put this in theme functions.php

add_action( 'woocommerce_before_calculate_totals','cp_add_custom_price', 10, 1);
function cp_add_custom_price( $cart_obj ) {
    //  This is necessary for WC 3.0+
    if ( is_admin() && ! defined( 'DOING_AJAX' ) )
        return;
        
    foreach ( $cart_obj->get_cart() as $key => $value ) {
        if($value['sample']){
            $product_id = $value['product_id'];
            $sample_price_mode = get_post_meta($product_id, 'sample_price_mode', true) ? get_post_meta($product_id, 'sample_price_mode', true) : 'default';
            $sample_price = get_post_meta($product_id, 'sample_price', true) ? get_post_meta($product_id, 'sample_price', true) : 0;
            if ($sample_price_mode === 'custom'){
                $price = $sample_price;
            }else if ($sample_price_mode === 'free'){
                $price = 0;
            }else{
                $price = $value['data']->price;
            }
            $value['data']->set_price( $price );
        }

    }
}

[Moderator note: code fixed. Please wrap code in the backtick character or use the code button.]

Hope this helps you…
