Magento – Magento 2 not spawning consumer processes i DB (RabbitMQ)

I have setup Magento 2.4 with RabbitMQ. You can see my configuration here.

'queue' => [
    'amqp' => [
        'host' => 'rabbitmq.host',
        'port' => '53003',
        'user' => 'username',
        'password' => 'password',
        'virtualhost' => '/'
    ],
    'consumers_wait_for_messages' => 1
],
'cron_consumers_runner' => [
    'cron_run' => true,
    'max_messages' => 20000,
    'consumers' => [
        'async.operations.all',
        'product_action_attribute.update',
        'product_action_attribute.website.update',
        'inventory.source.items.cleanup',
        'inventory.mass.update',
        'inventory.reservations.cleanup',
        'inventory.reservations.update',
        'inventory.reservations.updateSalabilityStatus',
        'inventory.indexer.sourceItem',
        'inventory.indexer.stock'
    ]
],

Magento 2 cron is running. You can see log here.

main.INFO: Cron Job consumers_runner is run [] []
main.INFO: Cron Job consumers_runner is successfully finished. Statistics: {"sum":0.0011739730834961,"count":1,"realmem":0,"emalloc":2960,"realmem_start":176685056,"emalloc_start":162316640} [] []

Any bulk actions that are added into table magneto_bulk are never executed. All product bulks updated stays pending.
All entries in queue_message_status stays with status code 2 (pending)

This is my consumer list.

$ bin/magento queue:consumers:list
product_action_attribute.update
product_action_attribute.website.update
exportProcessor
inventory.source.items.cleanup
inventory.mass.update
inventory.reservations.cleanup
inventory.reservations.update
media.storage.catalog.image.resize
codegeneratorProcessor
inventory.reservations.updateSalabilityStatus
inventory.indexer.sourceItem
inventory.indexer.stock
media.content.synchronization
media.gallery.synchronization
async.operations.all

Nothing happens when i try and run manuel with $ bin/magento queue:consumers:start product_action_attribute.update

I see no errors in logs.
If i use default MySQL message queues, i am supposed to see some idle procceses in DB, correct? I do not see any processes at all.

Where should i start to debug this issue?

halp!
