Intermittent Xamarin.iOS crash with no exception thrown

I have created a Xamarin.Forms barcode scanning app with Android and iOS projects. The Android build appears to run fine, but the iOS build occasionally crashes and I am struggling to pin down the cause, as no crash log is produced and no exception is reported in the application output.

Under heavy load (non-stop barcode scanning) the app crashes after typically 200 or 300 barcodes have been scanned.

I am puzzled how such a crash can occur, leaving absolutely no evidence of its cause. Is there somewhere else I should be looking for the evidence, apart from within Xcode's Devices window? Shouldn't I expect an exception to be reported in the application output, while debugging?

I have implemented logging handlers for AppDomain.CurrentDomain.UnhandledException and TaskScheduler.UnobservedTaskException but they don't appear to be called. Is there some other way I can instrument my code to trap the cause of this crash?

Many thanks for your advice, Tim

To get some output I always hit the continue button in visual studio debugger. The application stops, and for some reason I can see an exception in the output. Hope this helps.
