Avoid crashing when writing of config file fails

technically, you should wrap this in a try-catch block if your goal is to make it not crash. file existence is not sufficient.

I would just do:

try:
    with open(swagger_filename) as fh:
        self.__class__._swagger_spec = json.load(fh)
except Exception:
    try:
        Path(self.config.user_config_dir).mkdir(parents=True, exist_ok=True)
        with open(swagger_filename, "wb") as fh:
            fh.write(res.content)
    except IOError as e:
        logger.error(e)
    self.__class__._swagger_spec = res.json()
