Swarm Agent stuck on exporting to local cache

As in the topic, SwarmAgent works endlessly on exporting to local cache, some logs here:

Did you ever find a solution to this? I’m having the same issue.

that’s because of some damaged model or material, you have to clear the last added things and check exporting again, in my case they were rocks from the marketplace.
