Can’t launch C++ Windows project on Mac

We’ve used AI chatbots and all the forums known to man to try and get our Windows C++ project to build and run on a Mac but unfortunately nothing we’ve done is working. We’ve deleted saved, intermediate, and binary files, regenerated project files, set the XCode build target to PROJECTNAMEEditor > My Mac and consistently get the error/log:
Engine/Binaries/DotNET/UnrealBuildTool/UnrealBuildTool.dll -Target=UnrealBuildTool -Platform=Mac
No platforms specified for target

We’ve done everything we can think of to resolve this error short of installing the source build. If that’s what we need to do then we’ll do it but we don’t want to take that step unless it’s necessary as it’s a long process
