Having this same error message generated on my iOS 16.0.2. No effect on the app but don't know what caused this. I ensured the spoken content is on and the voices are downloaded.

Same issue here running iOS 16.0.2 on a real iPhone 12. In my case though there are only complaints and no real errors.

Same issue here, for my case though, I used self.navigationItem.setValue(true, forKey: "__largeTitleTwoLineMode") and this enables the large title to be displayed without truncation but incurs the same issue as yours. For mine however, untruncated titles work fine. I am also very confused.
