Until Plex fixes these issues, you can use Don't Panic:

See Numergy/signalslot@704926e. Edit your /storage/.kodi/addons/script.plex/lib/_included_packages/plexnet/signalslot/signal.py file and make sure that your connect method looks similar:

    def connect(self, slot):
        """
        Connect a callback ``slot`` to this signal.
        """
        if not isinstance(slot, BaseSlot):
            try:
                if inspect.getfullargspec(slot).varkw is None:
                    raise exceptions.SlotMustAcceptKeywords(self, slot)
            except TypeError:
                if inspect.getfullargspec(slot.__call__).varkw is None:
                    raise exceptions.SlotMustAcceptKeywords(self, slot)

It worked fine for me after that.
