I collect a lot of crash logs seem like this, but it seems that users are not affected by these crashes.
How it happened? I find a clue about this,
All crashes has Text to Speech function. my related code:
AVSpeechSynthesizer in watchOS seems easy to cause bugs.
Any suggest ? Thank you for help.

Code Block swift libAXSpeechManager.dylib 0x6e31adbc -[AXSpeechThread main] + 368 (AXSpeechThread.m:50)
All crashes has Text to Speech function. my related code:
Code Block swift func speak(_ announcement: String,preDelay:TimeInterval = 0, endDelay:TimeInterval = 0,lan:String = "", rate:Float = AVSpeechUtteranceDefaultSpeechRate,didFinish:((_ str:String)->Void)? = nil) { DispatchQueue.global(qos: .background).async { let utterance = AVSpeechUtterance(string: announcement.lowercased()) utterance.volume = 2.0 if(lan.count > 0){ utterance.voice = AVSpeechSynthesisVoice(language:lan) } utterance.preUtteranceDelay = preDelay utterance.postUtteranceDelay = endDelay utterance.rate = rate if let callback = didFinish { self.synth.speakUtterance(utterance){ synth,utt in callback("\(utt.speechString)") } } else { self.synth.speak(utterance) } } }
