Montana 7xx Crash in createSession()

We've received reports of an app crash on Montana 7xx (incidentally, using Russian language) when calling createSession:

try {
    session = ActivityRecording.createSession({:sport=>sport, :subSport=>subSport, :name=>name});
} catch(e) {
    sport = 0;
    subSport = 0;
    session = ActivityRecording.createSession({:sport=>sport, :subSport=>subSport, :name=>name});
}

The crash is occurring on what's listed here as line 2, and there are two concerns:

1. Why is the crash occurring here?
2. Should the error be handled by the try-catch?
