Codesign Error ARKit

I am new to Mac development. I just bought a Mac and a dev account for ARKit dev and want to explore Unreal as an option in this. I can not get the Github repo for ARKit to compile. I am getting this error.

CodeSign /Users/jasonodom/Desktop/UnrealEngine-dev-ar-kit/Engine/Binaries/Mac/ShaderCompileWorker.app
    cd /Users/jasonodom/Desktop/UnrealEngine-dev-ar-kit/Engine/Intermediate/ProjectFiles
    export CODESIGN_ALLOCATE=/Applications/Xcode-beta.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/codesign_allocate
    
Signing Identity:     "Mac Developer: Jason Odom (############)"

    /usr/bin/codesign --force --sign 6A30A4032F634414C6AB5B0E0E28F286D9D52F64 --timestamp=none /Users/jasonodom/Desktop/UnrealEngine-dev-ar-kit/Engine/Binaries/Mac/ShaderCompileWorker.app

/Users/jasonodom/Desktop/UnrealEngine-dev-ar-kit/Engine/Binaries/Mac/ShaderCompileWorker.app: No such file or directory
Command /usr/bin/codesign failed with exit code 1

It looks like ShaderCompileWorker.app is not appearing in the directory and so it can not be signed.

I have deleted and restarted from scratch multiple times, each with the same result.

Any ideas why this might be having issues.
