I also received a similar report from a user that the app crashes only on Apple Watch 10 devices that have updated their OS to version 11. It absolutely does not occur on other devices (Watch 7/8/SE2) that have updated their OS to 11. If you have improved the "_UIGraphicsBeginImageContextWithOptions" part, could you please help me with how you modified it? We haven't purchased the Apple Watch 10 device yet.

I also saw similar numbers. It's probably an error on the App Store Connect web page.

The moment you touch it for the first time, the previously drawn drawing disappears and appears again when you remove the touch from the screen. (See attached video)

Run the app again, create a new PKCanvasView, and put the saved PKDrawing into the drawing variable of the just created PKCanvasView.

Save the PKDrawing of PKCanvasView as separate data or file.

I would like to know if there is a way for the app to know when an emergency alert arrives.

Even after the 17.4.1 update, the same symptom continues to occur.

The issue occurred only in certain apps, so I contacted Apple.

The issue has not been fixed yet. For example, version 1.10 cannot create a new version as 1.11. Please fix it quickly

The issue was requested through the Apple Feedback app.

It happens on all iOS 16 devices. It happens easily if you play and stop it repeatedly. When playing, it seems that the error does not occur if AVSpeechSynthesizer is finely separated by spaces and played back. Errors do occur, but they may occur less frequently. I tested it with an app that plays TTS in that way, but the app didn't die. There are several symptoms when an error occurs. It can't stop playback, loses control, and continues to play until the end of a sentence. If an alarm or call comes in while TTS is playing, the phenomenon of listening through the earphones and playing back through the speaker also occurs. I temporarily took measures to prevent the above problem from happening without the app dying. A quick iOS update should fix this problem.
