Further investigation revealed that the issue was due to the lack of Bluetooth permission.
Sample macOS app should check for Bluetooth permission and request permission as needed.

Determined the issue by opening Console and going to Crash Reports for sensortag.kexe:

Workaround is to add terminal app to list of apps that are allowed Bluetooth access in System Preferences > Security & Privacy.
