HttpFoundation Session stand alone component and forms renderer - php

Question

(I deleted previous similar subject, because there was too many changed in the code).
I use Symfony\Component\HttpFoundation\Session\Session and Symfony\Component\HttpFoundation\Request but without all framework.
I have simple index
$request = Request::createFromGlobals();
$session = new Session();
if(!$session->isStarted()){
$session->start();
}
$request->setSession($session);
$kernel = new Kernel(new AppContainer());
$response = $kernel->handle($request);
$response->send();
it works well when I use just twig templates.
When I use any class what implements FormRendererInterface it throw me an error.
I expect that by CsrfTokenManager.
This problem doesn't exists when I use $session = new Session(new PhpBridgeSessionStorage()); in index.php. Unfortunately in such case sessions in the next request are empty (this is logic, because I sessions auto start in php.inii is disabled).
Bellow is code what I use in the controller to use form builder.
...
$form = (new LoginForm($this->formBuilder))->getForm($this->generateUrl('login'));
$form->handleRequest($request);
Match::val($form->isSubmitted() && $form->isValid())
->of(
When::equals(true, function($item) use ($form){
$this->commandBus->dispatch(new UserLogin($form->getData()));
}),
When::other(false)
);
...
Thanks for any hints.

SOLUTION
The issues was because to build form I use class FormBuilder what is abstract for others forms and it was provided as service.
There is creating csrf token and to do it I need to session instance.
I could not fond sessions in this class because it was configured in AppContainer.
So finally I had session what was start in the index.php and next try to start in the SessionTokenStorage. It has been throwed an error.
Now session is create in the AppContainer as public service.
I can set the same instance as parameter for others services and also add to the request by $appContainer->get('sessions').
Little bit of code
services.yaml
...
sessions:
class: Symfony\Component\HttpFoundation\Session\Session
arguments: []
public: true
form.builder:
class: Iaso\Web\Component\Form\FormBuilder
arguments: ['#twig','#config.loader', '#sessions']
public: true
index.php
<?php
...
$request = Request::createFromGlobals();
$appContainer = new AppContainer();
$session = $appContainer->get('sessions');
if(!$session->isStarted()){
$session->start();
}
$request->setSession($session);
$kernel = new Kernel($appContainer);
$response = $kernel->handle($request);
$response->send();
