If I am seeing

Uncaught Kotlin exception: kotlinx.coroutines.CoroutinesInternalError: Fatal exception in coroutines machinery for DispatchedContinuation[WorkerCoroutineDispatcherImpl@169bc08, Continuation @ $start$lambda-1COROUTINE$34]. Please read KDoc to 'handleFatalException' method and report this incident to maintainers

...

Caused by: kotlin.native.concurrent.InvalidMutabilityException: mutation attempt of frozen dev.williamreed.clique.mobile.WsSession.$start$lambda-1COROUTINE$34@3b34238

is this actually a bug in the library - or is the fault the "caused by" section from something I did?
