logging.config.dictConfig(config)ValueError: Unable to configure handler 'sink'
SimpleQueue does not implement the full Queue interfaces thus both isinstance(obj, queue.Queue) and the queue interface check fails.
Since this has been working on 3.8 - <3.12 I think the queue interface check is checking for methods that are not used at all and should be adjusted accordingly.
