Hello!
My app has been experiencing some strange crashes in the last few months. The crash log shows it as a Watchdog timeout error of 0x8BADF00D. I knew about this error code before, especially since here is the documentation about addressing-watchdog-terminations. But actually, the call stack shows that the crash appears in dydl and it seems that my app code has not been executed yet.
Does anyone know the cause of this problem please? I have observed this crash on iOS 15.6, 15.5, 15.4, and earlier versions.
