gardian206 & Kehel18. thanks for the suggestions, but I had already found these answers online, the problem with the methods mentioned is that these also do not resolve the problem permantly, Everytime after closing the UE5 project and reopening it again Im back to a situation where it does not immediately detects the c++ files.
Are you guys regenerating / “rebuilding” your project everytime before opening it up?
PS. The project is not under version control and was started as a C++ project.
