App freeze on first launch

[endore8]

On the first launch of my app (after reinstall as well), it would freeze immediately at the start and crash after a few seconds. Reopening it would have no issues.

After long debugging hours, I found out that it is caused by this library. By simply disabling code that initializes and uses Segment.Analytics the issue does not occur anymore.

The reproduction rate is at 100%. Interestingly, it is not reported by Crashlytics or Bugsnag.

I also noticed there is a network request to https://cdn-settings.segment.com, only at the first launch. The request never completes. Not sure if it is related to the issue, but seems weird.

This is a critical issue for us, as every user who installs the app, experiences a crash at the first launch!

Please advise a quick fix if possible, and have a look into the problem.

Thanks!

We're encountering the same issue: the app can be killed by the OS watchdog because of a lock in the Segment SDK.

We also recovered crash logs from user devices showing this issue. It does not show up in usual crash reporting tools because of the nature of the crash:
