Display category posts grouped by taxonomy

1. I’ve found a solution!

   <?php
       // Get current Category
       $get_current_cat = get_term_by('name', single_cat_title('',false), 'category');
       $current_cat = $get_current_cat->term_id;
   
   
       // List posts by the terms for a custom taxonomy of any post type
       $post_type = 'myposttype';
       $tax = 'mytaxonomy';
       $tax_terms = get_terms( $tax, 'orderby=name&order=ASC');
       if ($tax_terms) {
           foreach ($tax_terms  as $tax_term) {
               $args = array(
                   'post_type'         => $post_type,
                   "$tax"              => $tax_term->slug,
                   'post_status'       => 'publish',
                   'posts_per_page'    => -1,
                   'category__in'      => $current_cat // Only posts in current category (category.php)
               );
   
               $my_query = null;
               $my_query = new WP_Query($args);
   
               if( $my_query->have_posts() ) : ?>
   
                   <h2><?php echo $tax_term->name; // Group name (taxonomy) ?></h2>
   
                   <?php while ( $my_query->have_posts() ) : $my_query->the_post(); ?>
                       <?php $term_list = wp_get_post_terms($post->ID, 'category', array("fields" => "ids")); // Get post categories IDs?>
   
                       <?php if (in_array($current_cat, $term_list) ): // Display only posts that have current category ID ?>
                           <h3><?php the_title(); ?></h3>
                       <?php endif; // if in_array ?>
   
                   <?php endwhile; // end of loop ?>
   
               <?php endif; // if have_posts()
               wp_reset_query();
   
           } // end foreach #tax_terms
       } // end if tax_terms
   ?>
