How avoid error 404 after add post id to slug for custom post type? (post_type/%post_id%-%slug%/)?

Question

I want to have permalinks which will be look like: example.com/mypost/%post-id%-%slug%/

And the following code do it. But when I try to go to url of the post... I get error 404.

I have this code:

To register my custom post type function custom_post_type() {

// Set UI labels for Custom Post Type
    $labels = array(
        'name'                => _x( 'My Post', 'Post Type General Name', 'mypage' ),
        'singular_name'       => _x( 'My Post', 'Post Type Singular Name', 'mypage' ),
        'menu_name'           => __( 'My Post', 'mypage' ),
        'parent_item_colon'   => __( 'Rodzic ogłoszenia', 'mypage' ),
        'all_items'           => __( 'Wszystkie ogłoszenia', 'mypage' ),
        'view_item'           => __( 'Zobacz My Post', 'mypage' ),
        'add_new_item'        => __( 'Dodaj My Post', 'mypage' ),
        'add_new'             => __( 'Dodaj nowe', 'mypage' ),
        'edit_item'           => __( 'Edytuj', 'mypage' ),
        'update_item'         => __( 'Zapisz zmiany', 'mypage' ),
        'search_items'        => __( 'Szukaj ogłoszenia', 'mypage' ),
        'not_found'           => __( 'Nie znaleziono', 'mypage' ),
        'not_found_in_trash'  => __( 'Nie znaleziono w koszu', 'mypage' ),
    );
     
// Set other options for Custom Post Type
     
    $args = array(
        'label'               => __( 'myposts', 'mypage' ),
        'description'         => __( 'Ogłoszenia Nieruchomości w Holandii.', 'mypage' ),
        'labels'              => $labels,
        // Features this CPT supports in Post Editor
        'supports'            => array( 'title', 'editor', 'excerpt', 'author', 'thumbnail', 'revisions', 'custom-fields', ),
        // You can associate this CPT with a taxonomy or custom taxonomy. 
       // 'taxonomies'          => array( 'genres' ),
        /* A hierarchical CPT is like Pages and can have
        * Parent and child items. A non-hierarchical CPT
        * is like Posts.
        */ 
        'hierarchical'        => false,
        'public'              => true,
        'menu_icon' => 'dashicons-category',
        'show_ui'             => true,
        'show_in_menu'        => true,
        'show_in_nav_menus'   => true,
        'show_in_admin_bar'   => true,
        'menu_position'       => 25,
        'can_export'          => true,
        'has_archive'         => false,
        'exclude_from_search' => false,
        'publicly_queryable'  => true,
        'capability_type'     => 'post',
        'show_in_rest' => true,
        'rewrite' => array( 'slug' => _x('mypost/%post_id%','Slug myposts','mypage'))
    );
 
}

And for change the permalink (slug):

function custom_post_mycustomname_link($post_link, $post = 0, $leavename = false) {
    if($post->post_type == 'myposts') {
        return str_replace('%post_id%/', $post->ID.'-', $post_link);
    }
    else {
        return $post_link;
    }
}
add_filter('post_type_link', 'custom_post_mycustomname_link', 1, 3);

But the problem is that when I try to go to post I get error 404. I try to re-save premalinks in settings and it does not help. Can somone help?
