Symfony & Panther : Panther does'nt load - can't createPantherClient()

I have an issue with Panther in a Symfony 4.4 project. The project have LiipFunctionnalTestBundle on it, but for testing JS as well, i wanted to have Panther. I've installed Panther, in my composer i've "symfony/panther": "^0.8.0"," and i can extends my class with PantherTestCase or use PantherTestCaseTrait to have Panther and Liip (according to the documentation) https://github.com/symfony/panther But i'm not sure my project initialized Panther... If i do a simple test like :

<?php

namespace App\Tests\Controller\Social;

use Symfony\Component\Panther\PantherTestCase;

class PantherControllerTest extends PantherTestCase
{

    public function test1(): void
    {
        $client = static::createPantherClient(); // create your panther client

        $client->request('GET', '/login');
    }
}

I will have an error message when testing it :

1. App\Tests\Controller\Social\PantherControllerTest::test1 Symfony\Component\Process\Exception\LogicException: Output has been disabled. and it target the line with "createPantherClient".

If i tried to use Liip with WebTestCase and Panther in a Trait : it's working until i want to use specific assert from Panther. And then my IDE say 'assertSelectorIsEnabled' not found in NewsControllerPantherTest'. The method createPantherClient is not recognize, so even if i tried to put a localhost and a port to it, it doesn't work...

So i think Panther is in my project but doesn't load ? I'm in a windows pc with Mamp, php 7.4.1 and Apache.

I've put the tag in phpunit.xml.dist as say in the doc.
