Android: Fatal exception in coroutines machinery for CancellableContinuation

[nordfalk]

This exception has happened twice on a user's phone.
No one else has seen it (its running on 100 phones), and before and after it worked fine on this users phone.

Thank you for the issue. I’ll be able to check it on the next week

[nordfalk]

Sure!
Some more info:

The 2 crashes happened within 15 seconds of time. The users had used the app a long time before they happened
Startup

SD reports no problems at every invocation:

(numerouse use of coroutines)

Crash 1+2:

After the crashes the user was using the app for a long time, with no problems:

[nordfalk]

It was in Android 14:

I'll get back with more crash reports next week if it happens again

[nordfalk]

200 users have used it by now. No other crashes has occurred.
I'll get back to you by Friday or if another crash has occured.

[nordfalk]

No crashes since that first one 🥳
Next week I'll try with 1000 users and see how it goes, but it seems this was a one-time-issue.

[nordfalk]

Hi there,
Unfortunately the crash still sometimes appear:

The build with SD is currently running on 20% of our users.... so you can see that SD crashes would be completely dominant if I'd do a 100% rollout to all users.

Here are some stack traces from Google Play:

Even though it cant be see on the above stacktraces I have a suspicion that the problem is more appearent when using Jetpack Compose background coroutine tasks, such as LaunchedEffect...
