Workaround

regardless of what the problem might be, you're flagging this up against xamarin forms 5.0.0.2291 which is nearly 2 years old and many many versions out of date. whatever your issue might be, it could be that it has already been resolved if running a newer xamarin forms version. logging bugs against old versions is somewhat unproductive :/

[jfversluis]

As mentioned, this is an outdated version and without any reproduction or extensive logs there is not much useful I can say about this. It might be something in Xamarin.Forms, but it might as well be something in your code. Let us know if you have more information regarding this. Thanks!
