Hey -
We’re had other users reporting similar problems with creating code projects and I was trying to judge if it was specific to the launcher or GitHub source. This has been reported to our internal tracking database (UE-11475) for further investigation. You can try downloading the zip file of the source code and running both Setup.bat and GenerateProjectFiles.bat and then building the engine. If you’re still having the same problem I would suggest using a blueprint project or changing to another engine version to create a code project.
Cheers
