The project could not be compiled. Would you like to open it in Visual Studio?

Maybe provide some code ? BattleClicker.cpp line 8.

Maybe try to delete all of the temporary files created, you can try to open the project and select Clean from the Build menu.

Ok I will try that but this is so annoying

I believe that something similar has happened to me before. If the project is not compiling, then most likely there is an error in the C++ code. Go to your project file and open visual studio for that project, and look for the error to correct it. To avoid from this from happening again, remove errors and compile before closing visual studio/unreal editor.
