Help,I have encountered a thorny problem! In systems with iOS 16.5 and above, there is a probability that the keyboard will not disappear after it appears. And once it appears, unless the app is restarted, all places where the keyboard is used cannot be closed. I have tried using the forced shutdown method [UIView endEditing:YES], but it didn't work. When this exception occurs, I notice that there will be two UITextEffectsWindow at the same time. Does anyone know how to solve it?
