[Bug] java.lang.Throwable: Handle must be valid. Parameter name: type when calling Xamarin.Essentials.Preferences.Set

[IntegerOverlord]

Description

In my Xamarin.Forms project I get this error from users a lot:

Fatal Exception: java.lang.Throwable: Handle must be valid.
Parameter name: type
       at Java.Interop.JniEnvironment+InstanceMethods.GetMethodID (Java.Interop.JniObjectReference type, System.String name, System.String signature)(filename unknown)
       at Android.Runtime.JNIEnv.GetMethodID (System.IntPtr kls, System.String name, System.String signature)(filename unknown)
       at Android.Content.ISharedPreferencesInvoker.Edit ()(filename unknown)
       at Xamarin.Essentials.Preferences.PlatformSet[T] (System.String key, T value, System.String sharedName)(filename unknown)
       at Xamarin.Essentials.Preferences.Set (System.String key, System.Int32 value, System.String sharedName)(filename unknown)
       at Xamarin.Essentials.Preferences.Set (System.String key, System.Int32 value)(filename unknown)

I am unable to reproduce it myself, but there are more then a 100 of these reports. The bug happens on every version of Android

Also, I had the same issue with James Montemagno Settings Plugin:
jamesmontemagno/SettingsPlugin#152

Moving to Xamarin.Essentials didn't resolve it for me
And, I found similar issue with SecureStorage here, which was resolved:
#380

Expected Behavior

Preferences are saved

Actual Behavior

Crash

Do you have an example of usage?

[IntegerOverlord]

@jamesmontemagno hi! Yes, I use it like this

        public static int Transposition
        {
            get => Preferences.Get(PreferencesConstants.Transposition, 0);
            set => Preferences.Set(PreferencesConstants.Transposition, value);
        }

@jamesmontemagno I am unable to reproduce it myself, but in production this exception occurs quite a lot

[guillermo-gerard]

I found this issue and even though I'm not using Essentials, I want to share how I stopped this from occurring:
I was using just sharedPreferences as I'm working on a xamarin android app, and I was trying to write a value from inside a catch block.
I just took off that from the catch block and I stopped receiving this exception.
I hope this may be useful for someone else

[IntegerOverlord]

@guillermo-gerard I tried it in a test project, catch block doesn't cause any issues there

        void Button_Clicked(System.Object sender, System.EventArgs e)
        {
            try
            {
                throw new Exception();
            }
            catch
            {
                Preferences.Set("Test", "Test Value");
            }
        }
