Have same problem too.

This crashing stack trace doesn't contain any Firebase symbols except for Crashlytics' crash recording thread, which is most likely not responsible for the exception. Are you able to create a sample that reproduces this crash? If so, can you share it with us?

Hey @jiehu5114. We need more information to resolve this issue but there hasn't been an update in 5 weekdays. I'm marking the issue as stale and if there are no new updates in the next 5 days I will close it automatically.

If you have more information that will help us get to the bottom of this, just add a comment!
