Looking at the the art source it seems like this timeout when trying to set the thread name may be the culprit https://android.googlesource.com/platform/art/+/master/runtime/thread_list.cc#970

It’s not really clear to me whether this timeout would be triggered based on a specific state of the Thread or if it’s just a race condition that is sometimes triggered.

It seems like the thread name changing is mostly cosmetic? I wonder if an option to disable or reduce thread name changes might be a quick solution–as much as I would hate giving that up for debug purposes 😦

Get rid of Thread.name augmentation with CoroutineId when debug mode is enabled See #3677 and #2234 for the rationale Fixes #2234 — committed to Kotlin/kotlinx.coroutines by qwwdfsad a year ago

I am also facing the same not able to identify the issue. It occurs in production.

Thanks for pointing it out, it seems it’s worth adding a feature flag to disable thread name change.

As a workaround, it’s possible to disable the debug mode at all in the production builds to avoid that crash

@qwwdfsad how to disable this debug mode in prodution build?

We’ll provide either a workaround or will change the default behaviour in the next major version, thanks everyone for the reports!

Exactly the same crash as nimeacuerdo. Android 10 - 99.8 % Android 11 - 0.2

Mine is related to the R8 minifier (three shaking code it shouldnt), so I think my crash is unrelated to this. EDIT: It was: some custom proguard rules fixed it.
