How to redirect to different views based on user role or privilege in laravel 8?

I put the function below in the LoginController class to redirect users to different views, and when after login I got this 419|expired page

  protected function authenticated(Request $request, $user) {
        if ($user->PRIVILEGE == 'C') {
            return redirect()->route('/users');
        } else if ($user->PRIVILEGE == 'B') {
            return redirect('/blog');
        } else {
            return redirect('/');
        }
   }
