true, it happens to me only with images of that type (white image), previously generated by the same control.

Hi Marco Salvatori,

We have prepared a sample with the provided image and checked the reported problem with Syncfusion version 19.3.0.57. But we are not able to reproduce the reported problem on our side. Can you please check with the sample from the attachment? If still, you face the problem, please revert us by modifying the sample based on your application along with the replication procedure. This would be helpful for us to give a better solution to this. Also, clear the NuGet cache as per below KB.

KB Link: https://www.syncfusion.com/kb/6987/how-to-clear-nuget-cache

Note: We have tested the sample in Android versions 8 and 11.

we replicated the code within our APP and the error occurs.

Android 11

at this point, could it be some incompatibility with other nuget packages?

xamarin forms is up to date.

problem that occurs only with images created with your control.

[Marco Salvatori]

if it can help..

if i insert this istruction

        private void PhotoEditor_BeginReset(object sender, BeginResetEventArgs args)

        {

            args.Cancel = true; //It restricts resetting image to initial loaded image.

        }

error disappear but 'reset' not work...

[Marco Salvatori]

my actual workaround is insert this code:

        private void PhotoEditor_BeginReset(object sender, BeginResetEventArgs args)

        {

            args.Cancel = true; //It restricts resetting image to initial loaded image.

            PhotoEditor.Source = null;

            PhotoEditor.Source = imageSource;

        }

Hi Marco Salvatori,

Thanks for your update.

As we have mentioned earlier, the reported crash has been resolved in our 19.3.0.57 NuGet release itself. Also, we have tested the fix with the most recent version of Xamarin Forms, and it works perfectly. Could you please confirm whether the reported crash happens in the sample that we provided earlier or only in your application?

If the problem reproduces only in your application, we recommend trying to clear your system cache. So, please follow the below hide lines to remove the old cache NuGet and check your application with the latest NuGet version.

1.Uninstall the syncfusion NuGets and Xamarin.Forms NuGet installed in your application.
2.Clear your application NuGet cache using the KB https://www.syncfusion.com/kb/6987  
3.Clean your application.
4.Install the required syncfusion latest nugets and Xamarin.Forms NuGet to your application.
5.Check the reported problem.

Regards,
Eswaran.
