This?

enqueue-dev/pkg/amqp-lib/AmqpSubscriptionConsumer.php

Line 98 in e399498

if ($consumer->getConsumerTag() && array_key_exists($consumer->getConsumerTag(), $this->subscribers)) {

Please confirm which version on php-enqueue you're using. You can run composer info enqueue/* to get that information without looking through composer.lock file.

I've looked through the code and yeah, it seems that this particular array was simply not initialized :/

On your local copy you can simply initialize it - in constructor or as part of property declaration - and see if it helps and the library works. I'm not familiar with this code so I can't say for sure for myself.

    public function __construct(AmqpContext $context, bool $heartbeatOnTick)
    {
        $this->subscribers = []; // <--- Here
        $this->context = $context;
        $this->heartbeatOnTick = $heartbeatOnTick;
    }

If it's all that is required and it works properly after that, I'll provide a PR for you.
