I pushed a very simple TabbedPage on my navigation stack. When the page is closed, the app crashes with 

[ERROR] FATAL UNHANDLED EXCEPTION: System.ObjectDisposedException: Cannot access a disposed object.
Object name: 'TabbedPageRenderer'.
  at (wrapper managed-to-native) AppKit.NSApplication:NSApplicationMain (int,string[])
  at AppKit.NSApplication.Main (System.String[] args) [0x00041] in /Users/builder/data/lanes/5143/124197ee/source/xamarin-macios/src/AppKit/NSApplication.cs:100 
  at XFMacRepro.Mac.MainClass.Main (System.String[] args) [0x00017] in /Users/Michael/Projects/XFMacRepro/XFMacRepro.Mac/Main.cs:11 

I tested this in XF

The repro project from bug 60510 also demonstrates this issue. https://bugzilla.xamarin.com/attachment.cgi?id=25552
