XF.UWP crash when navigating back #380
Comments

Exception thrown at 0x76DA78A2 (KernelBase.dll) in BB.App.UWP.exe: WinRT originate error - 0x80004003 : 'System.NullReferenceException: Object reference not set to an instance of an object. |
馃悰 Bug Report
I have a XF.UWP application.
I am currently using v4.0.11, because with v4.1.0 it does not render any animation on UWP (I will file a separate bug report for that)
v4.0.11 can trigger a crash (unhandled nullref exception)
This happens when I quickly navigate away from a page with an Lottie animation.
On UWP it seems to need approx 200ms to start animating the visual after displaying the 'begin state'.
If I quickly navigate back (for instance with the back button on my mouse), and I am within this 200ms (the animation has not started yet), the app crashes with a nullref exception.
If I wait for the animation to start moving, and move back then, all is fine.
Expected behavior
no crash.
