UE4 Editor doesnt show C++ Classes Folder


I want to add a C++ Class to my project. So I go to file tab, click new C++ Class, choose parent and click create. It opens VSC with the code, but I cannot see the C++ folder in the editor, even though in the eye icon “Show CPP Classes” is checked. My compile button doesnt work either, simply does nothing.

What could be the problem?
