I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.

Thanks for reporting, @AswinMRathees. This looks related to #13675. Is it possible for you to provide a reproducible example or a complete stack trace?

[AswinMRathees]

@rizafran thanks for the response. This gets reproducible whenever you runs the app. Xcode will be showing the hang message.

[paulb777]

Does it help to update to Firebase 11.x?

[AswinMRathees]

hi @paulb777 , the issue is still persisting with 11 series

[paulb777]

11.11.0 had an additional fix. Either way, we'll need stack traces to help.

Hey @AswinMRathees. 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!

[AswinMRathees]

This issue can be reproduced in any device and can be viewed in Xcode whenever "FirebaseApp.configure()" is called. I have already attached screenshot from the framework's code where hang is reported
