There is high possibility that you are here because you read other blog post but they didn’t work as it happened with me, so I thought to write a blog post.

As per latest version of woocommerce, it itself hooks the post_class and add the ‘last’ and ‘fist’ class

add_filter( 'post_class', 'wc_product_post_class', 20, 3 );

So, if you hook post_class to remove first and last class then either you can remove the filter or you can add another filter

Here is a ref to this issue
