Goals

After upgrading the Facebook SDK from 16.1.3 to 16.2.0 in our latest version 3.122.0 we started to see this crash for some of our users in Firebase. The crash seems to happen at the app startup because we don't have any logs in Firebase Crashlytics.

Expected results

No crash should happen

Actual results
