This is caused by the wrong pyglet version; you need pyglet < 2.0, at the moment the latst version < 2.0 is 1.5.29

Pyglet 2.0 was a breaking change, changing to a more modern OpenGL version, which was also breaking, so the whole rendering stuff is not working with pyglet 2.0, including the fog.

If you used pip, first uninstall: "<python command> -m pip uninstall pyglet", and than reinstall the version you want by "<python command> -m pip install pyglet==1.5.29"
