Are you using Unity ? Did you ask them about possible cause of crash ?

I see crashes in __semwait_signal and in __ulock_wait in two different apps, not related to Unity. It started with iOS 15 and is not solved in 15.1. Crashes happen in Google Maps SDK and Airship SDK.

I've an app that hangs sometimes when AudioComponentInstanceDispose is called. The function just doesn't return and the system watchdog eventually shuts my app down. Though the crash reason may be different, that AudioComponentInstanceDispose hang time looks suspiciously similar.
Only happens on iOS 15. Am not using Unity.

A similar report is here: https://github.com/pjsip/pjproject/issues/2896

We continue to have problems determine the root cause of Intermittant APP crash. We were told to look at the Third Party SDK that opens and closes the Lidar camera. We have confirmed we are opening and closing the camera properly. We built a test app to open and close the app and it ran 150 times without a problem.

Could a thread that saves the JPG pictures as a video cause the sensor_stream to hang and crash the app? Here is snippets of the crash logs. Any further help would be appreciated.
