In my case I had no permissions errors. It had to do with a require() for disabled PHP functions in the pnctl-event-loop-emitter library. The composer autoloader was failing hard and crashed the script. The solution was to enable pcntl_ functions in php.ini.

The offending file was vendor/composer/../gos/pnctl-event-loop-emitter/src/functions.php
