I had that happen to me as well. Only solution i could come up with was installing from source. Here it is 3 days later and it finally works. And one thing is if your projects are in a different subfolder then they are suppose to be you have to tell vs studios community after building the project with your added c++ content (scripts) you more then likely will need to tell it where all the dependacies are or it’ll error and say your project was built from antother engine. Hope this helps.

You must added “EnhancedInput” Module to your #PROJECT.Build.cs Like This:

PublicDependencyModuleNames.AddRange(new string[] { “Core”, “CoreUObject”, “Engine”, “InputCore”, “EnhancedInput” });
