I think this is happening because Kacper only made conda builds for
python3.5, not python3.6. I *think* it will work if you downgrade python to
python3.5, and set up your python environment once again.
We should probably set up a conda-forge package for glfw and cyglfw3 so we
can automatically take care of these package updates.
