Thanks @dellis1972 this appears to have fixed the template generator hanging. Should the Android platform be selectable at this point or is that still a TODO? I don't have the Java dependencies installed so that could very well be a problem on my end.
Hmm, that looks like a bug. Only DesktopGL should be available atm. UWP should defiantly be disabled.. I'll fix it. But at least its kinda working now.
