Shopware 6 Import/Export Product Default Profile Export is stuck

Hey Guys,

When I export the default profile for products (I have 20,000 products in my shop), the export initially processes 4,000-5,000 products and then gets stuck for 30-60 minutes. It is the only entry in the messenger_messages table. After revisiting the shop and logging out, I come back after 1-2 hours, and the export is magically done.

I ran messenger:consume multiple times, but it didn’t work; the task ran but nothing happened. In the Network tab in the Administration, there were no network errors thrown.

Does anyone know how to figure out what causes this phenomenon?
