This is not a crash log, just profiling information that is collected to help investigate issues. It says that the process is being woken up frequently, which may explain actual problems like performance or battery issues in some cases. Having a microstackshot saved doesn't indicate a problem by itself.

The log shows camera capture and sending of an audio track through peer connection. It is not unreasonable to have important processing here.
