Custom post type permalink returns bad url

I have problem with custom post type. In BO url’s are ok example: page.pl/post_type_name/post_title.
When I try use get_the_permalink() or the_permalink() it return url like:
/?post_type=cpt_wydarzenia&p=258

Code:

    $args = array(
            "label" => __( "Wydarzenia", "vilo" ),
            'labels' => $labels,
            'hierarchical' => false,
            'supports' => array('title', 'editor'),
            //'taxonomies' => array( 'category', 'post_tag' ),
            'public' => true,
            'show_ui' => true,
            'show_in_menu' => true,
            'menu_position' => 5,
            'show_in_nav_menus' => true,
            'publicly_queryable' => true,
            'exclude_from_search' => false,
            'has_archive' => false,
            'query_var' => true,
            'can_export' => true,
            'rewrite' => array(
                'slug' => 'wydarzenia',
                'with_front' => true
            ),
            'capability_type' => 'post',
            'menu_i

          con' => 'dashicons-book',
                 'supports' => array(
                 'title',
                  'thumbnail',
            'comments',
            'editor'),
    );

    register_post_type( 'cpt_wydarzenia', $args );
    flush_rewrite_rules();

function get_future_permalink( $id ) {
    if ( $post = get_post( $id ) ) {
        $post->post_status = 'publish';
        return get_permalink( $post );
    }
    return '';
}
