Recently we had migrated our application from the .net 8 to the .net 9. we are having the web view in our application. in the .Net 8 the webview is working fine. where comes to the .net 9 the application is crashing while opening that page with the error
Microsoft.UI.Xaml.Controls.Frame.NavigationFailed was unhandled.
This is happening only in the windows applications. and working fine the android and iOS
Thank you.

be sure webview2 is installed on the client machine:
https://developer.microsoft.com/en-us/microsoft-edge/webview2?form=MA13LH
I don't have access to install the WebView2 in the client machines. Do we have any option to do that from the application side.?
See thread, it may be the issue
