Trying to Open UnrealProject from Windwos System with MacOS, but not working... I literally tried everything...

I need help so bad, my professor and me are struggling pretty bad with this issue. She gave me a Project Folder for Unreal, she works on Windows but I on MacOS.

Right Click on the .uproject and “Generate Xcode Project” is not working, it just opens a Terminal-Window?
Right Click on the .uproject and “Launch Game” is not working
Double Click on the project files to open also won’t start anything

I work with Xcode 26.01. and UE 5.6.1, I opened the .uproject with the TextEditor to check if the Engine is the right one - it actually is - “EngineAssociation”: “5.6”

When I create a new empty project file with C++ everything works fine, it opens up Xcode and UE.
But somehow this project I got from my professor is not opening.

I get an error “LivingRoom could not be compiled. Try rebuilding from source manually.”

What is the problem here? Can somebody help? I would be sooo thankful for every help, because this is urgent cause I need this for my SemesterProject…

hi, I can try to open it for you if you send it to me
