Unhandled Exception for on-device settings onBack function popView slide right

I received the following Unhandled Exception error in ERA:

Error Name: Unhandled Exception
Devices:
Venu® Sq: 3.30
App Versions: 1.1.4
Languages: ita
Backtrace:
AppSettingsMenu.onBack:435

It references the onBack function popView command for on-device settings:

Any ideas on what might have caused this error?
