How do I fix this?

I get this error message whenever I try to open a C++ project and it allows me to work in visual studio but it doesn’t let me work in UE like making a new C++ class or anything like that, has anyone else ran into this problem?

The project could not be compiled. Would you like to open it in Visual Studio?
