Rg.Plugins.Popup: System.NullReferenceException When trying to pop a popup

Hi,

🐛 Bug Report

On iOS 15, sometimes we got this exception when we try to pop a specific popup:

`Exception: System.NullReferenceException: Object reference not set to an instance of an object. at Rg.Plugins.Popup.IOS.Impl.PopupPlatformIos.AddAsync (Rg.Plugins.Popup.Pages.PopupPage page) <0x105f87294 + 0x00460> in <c764561bc21b420689a747c209523bf2#9d0a4ec250688d50b764561a6d88ab00>:0 at Rg.Plugins.Popup.Services.PopupNavigationImpl.AddAsync (Rg.Plugins.Popup.Pages.PopupPage page) <0x105f897e8 + 0x0003f> in <c764561bc21b420689a747c209523bf2#9d0a4ec250688d50b764561a6d88ab00>:0 at Rg.Plugins.Popup.Services.PopupNavigationImpl+<>c__DisplayClass20_0.<PushAsync>b__0 () <0x105f90804 + 0x0007b> in <c764561bc21b420689a747c209523bf2#9d0a4ec250688d50b764561a6d88ab00>:0 at Rg.Plugins.Popup.Services.PopupNavigationImpl+<>c__DisplayClass28_0.<InvokeThreadSafe>b__0 () <0x105f82440 + 0x0018b> in <c764561bc21b420689a747c209523bf2#9d0a4ec250688d50b764561a6d88ab00>:0 at Rg.Plugins.Popup.Services.PopupNavigationImpl+<>c__DisplayClass23_0.<RemovePageAsync>b__0 () <0x105f81c90 + 0x001e7> in <c764561bc21b420689a747c209523bf2#9d0a4ec250688d50b764561a6d88ab00>:0 at Rg.Plugins.Popup.Services.PopupNavigationImpl+<>c__DisplayClass28_0.<InvokeThreadSafe>b__0 () <0x105f82440 + 0x0018b> in <c764561bc21b420689a747c209523bf2#9d0a4ec250688d50b764561a6d88ab00>:0

Note we call “RemovePageAsync” and we got an exception from the “AddAsync” method.

Expected behavior

Pop the specific popup.

Configuration

Version: 2.0.0.13

Platform:

iPhone 11 Pro Max iOS 15.0.1
Xamarin.iOS 14.20.0.3

Thanks.

Just here to say this bug is not reproducing any more with the latest version

Having this issue on our production app on iOS devices 15+ massively. Turns out I have similar crashes in the code that references UIApplication.SharedApplication.KeyWindow

I have the same issue on my iOS 15+ device, but it is a race condition. If I click a button that will show a pop-up, right when the app started, then the KeyWindow is null and throws the exception. If I wait a few seconds longer, then it won’t happen as the KeyWindow is known then.

Its unusual how some production apps are having issues and some arent.

I haven’t noticed any production issues on any of my iOS 15 devices, however lets hope this sorts out this slippery issue
