System.ArgumentException: Handle must be valid. Parameter name: instance on CrossSecureStorage

[HadiHas]

Lately the xamarin android app is crashing randomly on CrossSecureStorage with error as below:

public static string CrossSecureUserTypeKey { get; } = "UserType"; //Located in Statics.cs var UserType = Plugin.SecureStorage.CrossSecureStorage.Current.GetValue(Statics.CrossSecureUserTypeKey);

Error:

System.ArgumentException: Handle must be valid. Parameter name: type at Java.Interop.JniEnvironment+InstanceMethods.GetMethodID (Java.Interop.JniObjectReference type, System.String name, System.String signature) [0x00009] in :0 at Android.Runtime.JNIEnv.GetMethodID (System.IntPtr kls, System.String name, System.String signature) [0x00007] in :0 at Android.Content.ISharedPreferencesInvoker.Contains (System.String key) [0x00012] in :0 at Plugin.SecureStorage.SecureStorage.HasKey (System.String key) [0x0000d] in :0 at drappme.MainActivity.b__40_0 () [0x00018]

any thoughts?

Probably need fix made in Xamarin.Essentials: https://github.com/xamarin/Essentials/pull/386/files#diff-57e97505a71d3732c6a7bf3fc654764e
