Hi @smartestimatorapp,

Thank you for reporting this issue. The crash you're experiencing with the SelectableWrapPanel inside a PopupPage is related to the Mopups library, as described in this issue.

To prevent the app from crashing, please add the following workaround code to your MauiProgram.cs file when the app is being created:

//Workaround for: https://github.com/LuckyDucko/Mopups/issues/97
#if IOS
    Mopups.Platforms.iOS.PopupPageHandler.Mapper.AppendToMapping("FixingMopupCrash", (handler, view) =>
    {
        (view as Page).Appearing += (s, e) =>
        {
            var eventName = "DescendantRemoved";
            var eventInfo = typeof(Element).GetEvent(eventName);
            var descendantRemovedEvent = typeof(Element).GetField(eventName, BindingFlags.Static | BindingFlags.Instance | BindingFlags.Public | BindingFlags.NonPublic);
            if (descendantRemovedEvent.GetValue(view) is not Delegate eventDelegate)
            {
                return;
            }

            foreach (var d in eventDelegate.GetInvocationList())
            {
                eventInfo.RemoveEventHandler(view, d);
            }
        };
    });
#endif
