Fresh Symfony install using:

composer create-project symfony/skeleton application 4.4.99

reconfigured App\Kernel with:

//use Symfony\Component\HttpKernel\Kernel as BaseKernel;
use Symfony\Component\HttpKernel\AsyncHttpKernel as BaseKernel;

and when running:

php vendor/bin/server 0.0.0.0:8100 --non-blocking --static-folder=public --bootstrap=symfony4

the result is:

Fatal error: Uncaught TypeError: Argument 1 passed to Symfony\Component\HttpKernel\AsyncHttpKernel::__construct() must be an instance of Symfony\Component\HttpKernel\AsyncEventDispatcher, string given, called in ~/projects/project/application/vendor/apisearch-io/symfony-react-server/src/Adapter/Symfony4KernelAdapter.php on line 39 and defined in ~/projects/project/application/vendor/apisearch-io/symfony-async-http-kernel/AsyncHttpKernel.php:64

Sorry for posting, this is not a bug at all, my mistake was replacing the kernel with

use Symfony\Component\HttpKernel\AsyncHttpKernel as BaseKernel;

when the line should have been:

//use Symfony\Component\HttpKernel\Kernel as BaseKernel;
use Symfony\Component\HttpKernel\AsyncKernel as BaseKernel;

Even though i will close the issue I will leave this here in case others also need to RTFM :)
