I am seeing this report in Bugsnag where the root exception is swallowed. Has anyone seen something similar before or have tips on how to best find the true root cause?

It looks like there's an uncaught exception in a CoroutineScope. konan::abort() indicates a fatal Kotlin exception. You can use something like NSExceptionKt or Kermit to log the Kotlin exception.

Wow, don't know how NXExceptionKt did not show up in my google search, but it's pretty much 100% perfect match for the problem I am running into. thank you! Looking forward to getting to identifying the root cause
