I can't open the C++ project in Unreal Engine4.26 on Mac

I would like to ask if any experienced individuals can help me solve this problem.

I tried to port a Windows project with C++ to Mac, but I couldn’t open it successfully on Mac. I searched for relevant information on the internet and tried various solutions, but I still couldn’t open it smoothly.
Here is the error message :

Even rebuilding it doesn’t allow me to open it.

In Xcode, the project fails to build because it can’t find MyMac. I tried changing the Executable in Edit Scheme, which works for UE4 but doesn’t work for the project.


During the process, I also tried to open a new project, but it still couldn’t be opened.
