My attempt to re-enable the Indigo MQTT has failed. Because of an unrelated incompatibility with the latest Indigo release, my Indigo version is 2022.2. I've deleted all copies of the Shelly MQTT and ShellyNGMQTT plug=ins, and deleted the trash. Joe Keenan said it looks like the problem is with the Shelly plug-ins.
The error messages are:

I've tried all the obvious - server stop/restart, reload the Broker and Connector plug-ins (compatible with Indigo 2022.2),
