MAUI CommunityToolkit Popup Not Reopening After Android Back Button Dismiss

[herczegzoltan]

I'm using .NET MAUI with CommunityToolkit.Maui.Core.Popup and created a popup service to open popups from the ViewModel, like this:

await _popupService.ShowPopupAsync(new MyPopup());

It opens correctly the first time, but when I dismiss it using the Android back button, the popup closes — and afterward, I can't reopen it anymore. No exception is thrown, but nothing happens, the button is not even enabled to press again.

I pass a new instance each time:

public interface IPopupService
{
    Task<IPopupResult> ShowPopupAsync(Popup popup);
}

public class PopupService : IPopupService
{
    public async Task<IPopupResult> ShowPopupAsync(Popup popup)
    {
        var page = App.Current?.MainPage ?? throw new NullReferenceException("MainPage is null");

        return await page.ShowPopupAsync(popup,);
    }
}

If in the the popup itself, I use Close(result) when dismissing manually (e.g., with a button) it works as expected and closes. But when dismissed via the back button it cannot be reopen anymore. Also the animation is different from regular closing.

I also tried wrapping it in try/catch but didn’t get any exception.
