CLOSED - Error when creating a UWP Game

Windows UWP
1

When I try to create a UWP Game for Windows 10 I’m getting the error
The file "D:\ProgramFiles\VisualStudio\Game1\Game1\project.json" wasn't found.

After the first error I’m getting a second error:
The method or operation is not implemented.

When I press ok (my only option), all my project files are gone and only the .sln file is left.

Which installer are you using?

I accidentally tried to install a Windows 8.1 UWP app instead of a Windows 10 UWP app. With Windows 10 UWP everything works fine.
