Popup message now working properly in WINUI 3 with UNO

[amit7775]

Below error coming when try to open popup ( NoDataPopup.IsOpen = true;)
Catastrophic failure (0x8000FFFF (E_UNEXPECTED))

but same code working fine on button click event
private void btnclose_Click(object sender, RoutedEventArgs e)
{
if (!ClosePopup.IsOpen)
{ ClosePopup.IsOpen = true; }

    }

and when we write same piece of code on if else condition then its giving error
If(result==true)
{
}
else
{
if (!NoDataPopup.IsOpen)
{
NoDataPopup.IsOpen = true; // Above Error coming in this line
}

            }

Thanks. The error you're getting is from WinAppSDK, not from Uno. It's likely that you can take a look at https://github.com/microsoft/microsoft-ui-xaml/issues and find your solution.
