Why do my c++ classes disapear

I have a problem with the editor. Every time I open it, the editor doesn’t show the C++ classes or even the C++ Classes folder. For them to appear, I need to create a new C++ class or recompile. However, all the Blueprints I’ve already created become invalid because they lose their parent class.

I’m using version 5.6.1.

ive had this problem adding c++ classes to a BP project, only solution for me was to always start a c++ project

Random idea: you may be building your project in DebugGame Editor, while by default *.project launches the Development Editor binaries. And since they were never built - engine can’t see your classes.

So, basically, try build Development Editor once

Thats the weird part it is a c++ proyect
