[Bug] Crash: IllegalArgumentException: Receiver not registered: android.hardware.camera2.CameraManager

Description

I am using Microsoft AppCenter and I have received the following crash report for my application. The application uses Xamarin.Essentials to turn on/off the flashlight. The app itself does not use a camera in any other way.

Exception: java.lang.IllegalArgumentException: Receiver not registered: android.hardware.camera2.CameraManager$1@8bacc91 Stack trace:

Android version: 6.0

The app works fine on the phones that I use for testing but all of them have a newer Android version (10). It is possible that the crash appears only in older Android versions.

Steps to Reproduce

I am not able to reproduce it on my phone.

Is there any progress on this bug? I have received several other crash reports. This time the device is AllView A5 Ready and the Android version is 6.0.

Any progress? I keep receiving other crash reports on various devices. The Android version is always 6.0 so the bug is probably specific to this version.
