Ok I fixed it by myself.
I deleted the Saved and Intermediate folder in my project folder and packaged it again.

You just fix my problem too!!!,

When I delete these folders, they get recreated whe I open the engine. What should I do then?

Using a bad .ico file as the game icon can also throw this error. In that case, just change the game icon back to the default ue4 image.
