and when I want open once again my project I get this message

When I confirm this I wait few secunds and rebuild failed.

Here are logs from editor when I create new C++ file:

I finally solved this problem , i added new C++ class(eg:slate widget) instead of empty c++ class.

Officially tutorial told me that i should create empty c++ class. But this doesn’t works for me.

Hope this help for you .And tell me if this works.

Sorry for my careless , The correct way is delete “Saved ， Intermediate" folder in you folder .Then add c++ class in your project.
