@sangitamalviya there's a new version for Reunion 0.8 as well for 7.0.3, do you see the same issue there?

Can you also provide the details from the exception and stack trace. You can inspect the e parameter to the UnhandledException to get those.

FYI @azchohfi

hi @michael-hawker, I have updated ProjectReunion with version 0.8.0 still it's giving exception.On e parameter it shows Element not found. (0x80070490)

Hello @sangitamalviya. This is a known issue. The InfiniteCanvas control doesn't work in WinUI3 and will not work until WinUI3 supports Inking (Microsoft.UI.Xaml.Controls.Ink* such as InfiniteCanvas, InkSynchronizer, InkToolbar, etc).
