Auto-Routing don't work with 4.4.0

I've just test with a fresh project and can reproduce it simply.
So, I download CI 4.4.0 and set only this :

In .env

PHP Code:

CI_ENVIRONMENT = development 


In Config\Routing.php

PHP Code:

public bool $autoRoute = true; 


In Config\Feature.php, the parameters still set to Legacy

PHP Code:

public bool $autoRoutesImproved = false; 


Then, I create an Auth.php file in app\Controllers\ folder

PHP Code:

<?php

namespace App\Controllers;

class Auth extends BaseController
{
    public function index(): string
    {
        return view('welcome_message');
    }
} 


When I want to access http://localhost:8080/auth, I have a 404 page with this message

Code:

Controller or its method is not found: \App\ControllersAuth::index
