Hello,

In my testing, After I removed the following code from AndroidManifest.xml:

   <receiver android:name=".BootReceiver" android:enabled="true" android:permission="android.permission.RECEIVE_BOOT_COMPLETED">  
   	<intent-filter>  
   		<action android:name="android.intent.action.BOOT_COMPLETED" />  
   		<category android:name="android.intent.category.DEFAULT" />  
   	</intent-filter>  
   </receiver>  

and added the following code in Receiver1.cs, the application could successfully deploy to my Android Emulator.

   [BroadcastReceiver(Name = "com.my_app.app.BootBroadcast", Enabled = true, Exported = false)]  
   [IntentFilter(new[] { Intent.ActionBootCompleted })]  
   public class BootReceiver : BroadcastReceiver  

The reason is that you need to set a value to the property export in using API 31 or above. and you can refer to this documentation Working with the Android Manifest to find this:

Xamarin.Android helps to minimize this difficulty by allowing you to add custom attributes to your classes, which will then be used to automatically generate the manifest for you. Our goal is that 99% of our users should never need to manually modify AndroidManifest.xml.

For this reason, we should try not to modify AndroidManifest.xml if we can.
