I am having trouble getting UE4 to package any projects on my machine. No matter what project even a blank clean project I get this error right away within seconds of starting the package.
UATHelper: Packaging (Windows (64-bit)): ERROR: System.ArgumentException: An item with the same key has already been added.
I’m running UE4 on a Windows 10 with Bootcamp on a MacPro, never had an issue packaging projects before on this machine. I’ve recently had to reinstall windows 10 whichever since then I’ve noticed the packaging error.
