I suspect you're using an outdated version of the Arduino framework.

[farfarfromhome]

That was it. Thanks for your quick response. I am hoping your library will fix instability I see with AsyncMqttClient.

[bertmelis]

fingers crossed. You're on esp32 so probably no need to use the async version and it will be more stable.
