Alloy - "Application Installer abnormal process termination" build error

I'm getting an error when I attempt to run an Alloy application on an Android emulator. The app was working as recently as yesterday although changes to the app have been made since then. I'm just not even sure where to start since the below stack trace seems to be pointing at an error in the Alloy compiler.
