Could you share the entire log? Ideally attach it as a separate file, otherwise formatting breaks.

You could try to build UE5 separately and then try to open CARLA afterwards.
For now update to the latest CARLA commit and try again, I've made some changes to the Setup script.
If it still fails, try running make in the UE5 folder for now. Then directly use CMake commands to build CARLA.
