\Amp\Parallel\Worker\createWorker() just hangs

[pachanga]

Hi!

I'm trying to follow an example and it seems my script simply hangs on the line:

$worker = \Amp\Parallel\Worker\createWorker();

I'm using PHP 8.3 without any special paral extensions, non ZTS. I'm using v2.3.1 version of amphp/parallel on Mac M2 mini.

Do you have a fully runnable example?
