I don't believe this is correct. All of the PAHO.MQTT functions are SYNC and handled via an independent thread and not the ASYNC.loop.

Can you elaborate on what led you to this change?

Confirmed this resolves breaking change.

Out of curiosity, I reloaded this integration to get/see the error:

The error is actually @ Line 230.

That error is actually in relationship to async_create_task being called from a thread. See additional fix details here.
