What is the best way to convert blueprint to c++

Hello internet, I need your expertise,

I have been trying to convert blueprint to c++ using nativization without any luck, it keeps giving me unknown error in the packaging process. Is there any other way to convert blueprint to c++ other than nativization?

If there is none and I have to do it manually, then what are the shortcuts and tools that I can use to make the process quicker.

You cannot convert Blueprint to C++ in the editor, only when you build the game
