Woocommerce pagination not working?

Question

WordPress

Hello. I display products from Woocommerce via WP_Query (), the design is as follows:

$category = get_queried_object();
$paged = ( get_query_var( 'page' ) ) ? get_query_var( 'page' ) : 1;
$args = array(
     'post_type'         => 'product',
     'paged'             => $paged,
     $category->taxonomy => $category->slug,
);
$posts = new WP_Query($args);
if($posts->have_posts()):
     while($posts->have_posts()): $posts->the_post();
          get_template_part( 'templates/content/product-cat', 'product-cat' );
     endwhile;
wp_reset_postdata();
endif;

Below I am trying to display pagination using the_posts_pagination() function . Nothing is displayed on the page at all, I tried not to interfere with the standard WP_Query () at all, that is, the design was like this:

if(have_posts()):
     while(have_posts()): the_post();
          get_template_part( 'templates/content/product-cat', 'product-cat' );
     endwhile;
wp_reset_postdata();
endif;

I also don’t want to display pagination, although in $paged I get int(1) , and in $posts->max_num_pages I have float(2) , I tried to use kama_pagenavi() , pagination is displayed but when I go to the second page they are displayed the same items as the first one. Tell me please, what could be the problem?
