This is probably more to inform.
We get this error on .NET SDKs 9.0.202. This issue may be resolved in 9.0.203 with a workload update for iOS which should update the native bindings.
Unhandled Exception:
System.MissingMethodException: Method not found: void AVFoundation.AVCaptureConnection.set_VideoRotationAngle(System.Runtime.InteropServices.NFloat)
at BarcodeScanning.BarcodeView.__Registrar_Callbacks__.callback_2_BarcodeScanning_BarcodeView_LayoutSubviews(IntPtr pobj, IntPtr sel, IntPtr* exception_gchandle)

However, this means that people using < 9.0.203 will experience this runtime native crash.
I have not verified if this does work on 9.0.203 due to local environment restrictions.
It works fine on 2.1.8 pre this commit: 8a7ce89
