Workaround

Please, make sure of having a full backup of your site before proceeding.

• Open …/wp-content/plugins/customer-reviews-woocommerce/includes/blocks/class-cr-reviews-grid.php file.
• Look for line 148.
• After this block of code:

  			$args = array(
  				'status'      => 'approve',
  				'post_type'   => 'product',
  				'meta_key'    => 'rating',
  				'orderby'     => $order_by,
  				'post__in'    => $post_ids,
  				'comment__not_in' => $comment__not_in
  			);
  

• Add this:

  			if (is_array($args['post__in']) && count($args['post__in']) === 1) {
  				$args['post_id'] = array_shift($args['post__in']);
  				unset($args['post__in']);
  			}
