Class 'Symfony \ Component \ EventDispatcher \ Event' not found

[Skreiphoff]

Error on request, tried to install EventDispatcher separately, but did not help.
My code;
`protected $client;

public function __construct()
{
    $this->client = new Client();

    $this->client->authenticate(getenv('TRELLO_API_KEY'), getenv('TRELLO_TOKEN'),Client::AUTH_URL_CLIENT_ID);
}

public function createCard(Task $task): array
{
    $this->client->api('members')->boards()->all('me');
    dd( 1);
}`
