Restarting the engine makes c++ classes not visible from the content browser

After creating c++ classes, if the engine is restarted, the c++ classes will not be visible in the content browser. However, the created classes are visible from the explorer. After opening the engine, if user recompiles in the editor, character c++ classes (MyCharacter.cpp) loads in the engine, however, empty c++ classes do not load after recompiling.

Issue does not occur in 4.27.

1. Create a C++ Project
2. Create a C++ Class
3. Restart Engine

Actual Result: After restarting the engine, c++ classes are not visible in the content browser but are visible from explorer window
Expected Result: C++ classes are visible from the content browser
