I am currently using version 124.0.5. My chat app is crashing in Android (pixel 5 & 8) about 1 in 20 calls. IOS has no issues.

Would anyone know how to avoid the scenario triggering the SIGABRT below?

If of interest, the webrtc specific typescript integration can be found here: [(code)](https://github.com/balzack/databag/blob/main/app/client/mobile/src/context/useRingContext.hook.ts)

I captured these logs in the most recent crash:

Any help would be greatly appreciated. Thank you! - Roland (balzack) Osborne

I delayed the InCallManager.start a little, and the race condition (crash) seems to not occur anymore. Perhaps this is now resolved….
