iOS Crash (reported via Apple)

(NB: I may have picked the wrong component above.)

I have a crash report received via Xcode for my published app. Here is the crash report. I have anonymised the app name and bundle ID. I can see from the threads that the app was fully up and running, as there are a few of my API threads going. The crash is in thread 0 and looks like it is related to an Undo gesture by the user. (Probably accidental, like shaking the iPad, but could have been genuine if within a QML TextInput or TextEdit.)
