iPhone XS Max crash

I complied an iOS app and try to deploy to different device.
But one of devices is iPhone XS Max with iOS 12.1.4.
When the app open in this device, the app crash immediately.
What should I do?

I am guessing the problem is due to the device is using A12 CPU which require the architect is ARM64e
but i do not find it in my visual studio.
XCode version 10.2.1
Xamarin iOS version 10.2.4
