Hi!

Are those crashes from production or your tests? Does it happen always or under certain conditions? Can you share and ask file and steps to reproduce?

Thank you!

Hello, Those crashes are from real devices in Debug mode. It randomly happen on my phones. So Do you have any solution to avoiding this crash in Production?
P.s: I have not seen this issue on production ( Firebase report) yet.

Can you check if your apk contains a- and b- files under com/appsflyer/internal? Not in classes.dex, but as binary resources. Here is what I mean - https://dev.appsflyer.com/hc/docs/install-android-sdk#missing-resource-files

I see it in APK Debug.
