I can’t package my project. The Error that I am getting says. ERROR: System.ArgumentException: An item with the same key has already been added.
I tried to rename my project following this tutorial. UE4: How to Rename Your Project in Unreal Engine 4 [Tutorial] - YouTube
It wouldn’t package so I tried renaming back to the old name.
HELP!
