Xamarin android crashing off debugging

Question

I am creating a Xamarin android application it worked fine for a long time but now it is crashing when I run it without a debugger attached (installed on device) and working fine while debugging with visual studio (connected to the laptop). What seems to be the problem.

here is my androidmanifest.xml file for a look

According to the code you provided, we could not find what cause this issue. Could you provide more details? Have you test with the sane version of the device and emulator? When you use the debugger with device, do you get the same error? — Wendy Zang - MSFT, Jul 26 '21 at 09:40
Thanks, but the problem is solved, I explored the Cat Log while launching application and found that the error was due to the null value provided to the newtonsoft.json deserializer. — Asad Ullah, Jul 26 '21 at 09:45

The problem was not with the AndroidManifest.xml file or application build settings, it was due to the null value object at main activity. PS: Discovered it by viewing Cat Log while launching the application on mobile without debugging.
