Hello Abdou,

Thank you for the provided image. 

I have tested the described scenario and I reproduced the exception with Xamarin.Forms 3.5 when RadListView and RadTreeView controls are used.

I have logged this issue on your behalf in our Feedback portal and you could follow the item on the provided link below:

You can find your Telerik points updated for bringing this to our attention. I can assure you that I have raised its priority and a fix for it will be provided in the next minor release. 

Currently, the workaround I could suggest you use the Xamarin.Forms 3.4. 

Let me know if you have any additional questions or concerns. 

Regards,
Sisi
