This is happening to my app lately quite a lot. The actual problem is a conflict between initial page navigation and deeplink navigation. When both try to navigate at the same time I get the exception.

I could not reproduce it until I enabled "Don't keep activities" in the phone dev settings, as @Sasha111ua pointed out (good catch btw). That forces the Android activity to be destroyed when the app goes to background.

Once thing I noticed is that Forms application remains in memory after the Activity is destroyed, which causes issues on my navigation logic (I rely on current page which stills exists but a new Forms app gets created).

Ideally the Forms app should be disposed as soon as the parent Activity is destroyed.
