SwipeView inside Popup crashes on Windows with System.AccessViolationException

Is there an existing issue for this?

Current Behavior

On Windows, opening a Popup containing a SwipeView crashes with "System.AccessViolationException: 'Attempted to read or write protected memory. This is often an indication that other memory is corrupt.'"

The same code works on Android.

Expected Behavior

Should not crash on Windows.

Steps To Reproduce

1. Build and run the repro app on Windows.
2. Press the button to open the popup. The app crashes.

Environment

- .NET MAUI CommunityToolkit: 9.0.0
- OS: Windows 11 Build 10.0.22631
- .NET MAUI: 8.0.40

Anything else?

The crash happens in the call to FrameworkElement.Measure() on the SwipeView. It may be a bug in MAUI, but I am posting it here because it only happens in a Popup.

Could be related to dotnet/maui#16735 ; the repro app is modified from that issue. However I can no longer reproduce the original issue.
