Unexplained rise of 'Non-fatal Exception: java.lang.Exception com.google.ar.core.exceptions.FatalException'

[agGitHub]

SPECIFIC ISSUE ENCOUNTERED

Since a date between Dec 4th 2024 and Dec 12th, I have a sudden rise of a crash in Firebase Crashlytics. This rise is not linked to an update of our app as it has not been updated during this period. I see that:

• the ARCore app on Google Play has been updated on Dec 4th https://play.google.com/store/apps/details?id=com.google.ar.core
• the ARCore SDK release occurred on Dec 12th: https://github.com/google-ar/arcore-android-sdk/releases

Noe that it is not sure if this problem induces a crash ; indeed the Crashlytics crash log below shows that the error is described as both "fatal" and "non fatal". We have not received any complains so we expect that the issue is non fatal but not sure. Also, Crashlytics shows that our "Crash free user rate" remains close to 100% and didn't change in December 2024.

Crashlytics also does not show any rise of the ANR rate in December 2024.

According to Crashlytics, this error happens with approximately 3.5% of our users.

Note that in Android Vitals (Google Play Console), we don't see any rise of the crash rate but we see an unexplained rise of ANR from Dec 10th. It is very weird as, as already explained, we see the contrary in Crashlytics: rise of the crash rate (not sure if fatal or not) and stable ANR rate.

Please tell us what is happening, solve the issue or tell us how to solve it. Thanks a lot.
