Problem with CI4 session

Do not know why, the session in the constructor is not working but in other method. Help me to find this out. Thanks in advance.

PHP Code:

<?php

namespace App\Controllers;

class Manage extends BaseController
{

 protected $session;

 public function __construct(){
     $this->session = \Config\Services::session();
     if( !$this->session->has('isCnProL') ) return redirect()->to(base_url('login')); // Not working
 }

 public function new_post()
 {
     if( !$this->session->has('isCnProL') ) return redirect()->to(base_url('login')); // Working
     $this->manageView('post-new');
 }
