From your log I can get two issues I would investigate further:
LogTemp: IPP ERROR: Could not find provision directory 'C:\Users\kkoud\AppData\Local/Apple Computer/MobileDevice/Provisioning Profiles/'.
[...]
UATHelper: Packaging (Windows (64-bit)): UnrealBuildTool: ERROR: Windows SDK v8.1 must be installed in order to build this target.
Starting with the latter one I would check the Win SDK installation and reinstall it if required. If you are trying to target iOS you should also verify the presence of the provisioning profiles, otherwise it might be advisable to ensure this platform is disabled in your project settings.
