Well, it’s not part of the standard or empty project templates, so it must have come from some additional content or plugin you have downloaded or purchased or installed or enabled.
Try this:
- Create New Project
- Choose First Person Template
- Save the default level
- Choose “package → Windows”
Does this also generate the error? If it does, then something has been installed/mutated in your engine installation. If this works, then the problem is in your project setup.
