As noted in the instructions - some versions, especially older ones, break in fun ways if you try to compile them with VS 2019. They were released before VS 2019 existed, and I guess they weren't updated.

(I am curious to know if building from the Unity GUI on these versions breaks with VS 2019 in the same way, or if it magically works somehow?)

To make group 3 build I had to uninstall the VS2019 C++ tools, however the VS2019 installer lets you install the VS2017 C++ tools and this enabled the build!
