Bluepy error after apt update && upgrade

I updated and upgraded the RPI and now I get this error after launching the daemon:

Xiaomi Mi Flora Plant Sensor MQTT Client/Daemon

    raise BTLEInternalError("Helper not started (did you call connect()?)")
bluepy.btle.BTLEInternalError: Helper not started (did you call connect()?)

The above exception was the direct cause of the following exception:
