We can not repro it for now. Stack trace from our crash reports:

Hi Andrey, 

I will need more details on the scenario in which the exception message occurs. Send me a sample app in which the issue happens, so I can further research this. 

If you do not want to attach the ticket in the forum, open a support ticket and attach the project to it. To reduce the file size, delete bin and obj folders and archive the project.

Hi Didi, I will try, meantime the stack trace says nothing to us, looks independend in Telerik Maui.
