Hi Ziqiao, thanks for the reply! We had opened some feedback issues where we shared some sysdiagnose files FB17994319 and FB18441142. The model is valid and works on other iOS versions, so it’s likely not corrupted. Nonetheless we’ll follow step 2 as suggested to double check and analyze it better. This issue, last week, affected ~15,000 users on iOS 26, while it works fine for others. It seems something specific to iOS 26 might be causing it. Any help would be greatly appreciated!
