codeception + enqueue/async-event-dispatcher = Fatal error

[mihas2]

i use codeception 4.1 + codeception/module-symfony 2.0 + enqueue/async-event-dispatcher 0.10.8 + symfony 5.3 and when running tests I get this error
Fatal error: Declaration of Enqueue\AsyncEventDispatcher\AsyncEventDispatcher::dispatch($event, $eventName = null) must be compatible with Symfony\Component\EventDispatcher\EventDispatcher::dispatch(object $event, ?string $eventName = null): object in /var/www/ms-notifier/vendor/enqueue/async-event-dispatcher/AsyncEventDispatcher.php on line 16

I think it's all about the module enqueue/async-event-dispatcher, which in one version tries to support different versions of symfony
if (class_exists(Event::class)) { /** * Symfony < 5.0. */ ... } else { /** * Symfony >= 5.0. */ ... }

If this is the cause, should be fixed by #1239
