console errors running craft.exe

I have followed the steps for the Python example until I am running the compiled craft.exe.

Already when I run the craft.exe, I get the following error in the console (running under windows 10, Python 3.6)

slider receives focus
Traceback (most recent call last):
  File "craft.py", line 338, in sliderFocus
  File "craft.py", line 353, in changeTool

  File "websocket\_app.py", line 344, in _callback

Then, everytime I click on something in craft.exe, I get the following:

Slider receives focus
Traceback (most recent call last):
  File "craft.py", line 338, in sliderFocus
  File "craft.py", line 353, in changeTool
  File "websocket\_app.py", line 156, in send
websocket._exceptions.WebSocketConnectionClosedException: Connection is already closed.

any idea what I need to change? Is this the same issue as https://github.com/Logitech/logi_craft_sdk/issues/22? The errors are slightly different though?
