[Solved] wpDiscuz doesn't load on Glossaries

Hello,

i am using wpDiscuz and have added support for the post type Glossary which is shown in the Form:  https://scrnli.com/files/RS9ek0AyUUgQ6n

I did this by using these PHP Codes:

/**     
 * Display the comment template with the [ wpse_comments_template ] shortcode. Note: Remove the spaces between the shortcode and [] brackets.
 * shortcode on singular pages. 
 *
 * @see   https://stackoverflow.com/a/28644134/2078474  
 */
 add_shortcode( 'wpse_comments_template', function( $atts = array(), $content = '' )
 {
    if( is_singular() && post_type_supports( get_post_type(), 'comments' ) )
    {
        ob_start();
        comments_template();
        add_filter( 'comments_open',       'wpse_comments_open'   );
        add_filter( 'get_comments_number', 'wpse_comments_number' );
        return ob_get_clean();
    }
    return '';
}, 10, 2 );

function wpse_comments_open( $open )
{
    remove_filter( current_filter(), __FUNCTION__ );
    return false;
}

function wpse_comments_number( $open )
{
    remove_filter( current_filter(), __FUNCTION__ );
    return 0;
}
function my_wpdiscuz_shortcode() {
  if (file_exists(ABSPATH . 'wp-content/plugins/wpdiscuz/templates/comment/comment-form.php')) {
      ob_start();
      include_once ABSPATH . 'wp-content/plugins/wpdiscuz/templates/comment/comment-form.php';
      return ob_get_clean();
  }
}
add_shortcode('wpdiscuz_comments', 'my_wpdiscuz_shortcode');

function comment_support_for_my_custom_post_type() {
   add_post_type_support( 'glossary', 'comments' );
}

add_action( 'init', 'comment_support_for_my_custom_post_type' );

But the form still doesn't show:  https://www.gooloo.de/inci/acetic-acid
