Thank you very much for your time. The issue is still unresolved. I tried using the Instruments memory tool and enabled malloc scribble, but unfortunately, the crash has not been reproduced yet. By the way, there is a crash on the iOS 26 system, and the crash stacks for iOS 26, 18, and 17 are the same as the ones I sent earlier. I noticed that on systems below iOS 17, the crash stack has changed to a different form, and the crash occurs in [AXSpeechThread main] (in libAXSpeechManager.dylib). I have attached the crashes for iOS 26 and iOS 16. Could you please provide guidance? iOS16-AXSpeechThread-Crash.txt iOS26-crash.txt

Thank you very much. This issue has been troubling me for months. My app frequently uses TTS, and the crash report has been attached. If you need more detailed information, please contact me. Additionally, I suspect it is a thread safety issue. I have tried making some calls on the main thread, but it hasn’t worked. I have also attached the code separately as an attachment.
