celery worker not consuming tasks from rabbitMQ queue

I have a queue in RabbitMQ broker called queue-ktm of type quorum. There are tasks pushed to this queue and available.

I run a celery worker to consume from this queue with following configuration:

app.conf.task_queues.extend([
    Queue("queue-ktm", exchange=Exchange('exchange-ktm', type='topic'), queue_arguments={'x-queue-type': 'quorum'}, routing_key='#'),
])

There's a binding to this queue from exchange exchange-ktm and key #.

I run the worker command:

celery -A celery_app.celery_app worker -Q queue-ktm --loglevel=debug

the worker lists the queue:

[queues]
.> queue-ktm exchange=exchange-ktm(topic) key=#

But the worker is not processing any task from the queue.

Checked the queue and Consumers are 0.

This became the issue when I switched from classic to quorum type.

Can anyone point the issue?
