        <input class="widefat" type="text" name="kral_product_name" id="kral_product_name" value="salaaaaaaaaaaaaam" />
    </p>
<?php
}

Solution

You are using the wrong post type value as screen value and the wrong context value.

The correct screen name will be comment not product-reviews

WordPress Documentation says that you can use side as context value when adding meta boxes on the comments page but I am not sure why it doesn't work with the side value.

Correct add_meta_box code will look like this:

add_meta_box(
    'kral_product_review',
    'اطلاعات دیدگاه',
    'kral_product_review_fields_metabox',
    'comment',
    'normal',
);
