This isn't an issue with the library, but with Flutter's Accessibility support for Windows.

Could you file an issue there with reproducible steps? I imagine this is due the Semantics widget being removed and added to the tree. Although I imagine this is only an warning!

[jonahzheng]

thank you, yes, but it seem not only an warning,
my steps:
1、run https://github.com/bdlukaa/fluent_ui/tree/master/example;
2、click NavigationPane's search icon, open NavigationPane;
3、and close NavigationPane, will occus issue.

Try the steps a few times, the app will exit autometically.

Flutter version 2.10.0
