I'm having the same problem with my company's app. Xamarin.iOS version: 14.20.0.24 and Xamarin.Forms: 4.7.0.1351.

I haven't really been able to find anything yet on what could be causing the issue.

We are seeing this issue as well on ALL our Xamarin Forms apps currently on the AppStore when installing on a device with the latest iOS 15 Beta 6 (to be clear we have not tested Beta 5 so it could be present there as well).

To rule out any third party issues I tried with a completely new empty app built on iOS SDK 14.5 and Xamarin Forms 5.0.0.2083 and deployed to a device with iOS 15 Beta 6 and I get the exact same issue. I even tried to install a couple of other apps from the App Store that I know are developed with Xamarin Forms and I get the same behaviour there. So as far as I can tell this is affecting many or maybe even all Xamarin Forms apps.

Does anyone have any thoughts on how to proceed with this? iOS15 release is coming closer and I am starting to get a bit nervous here...

We are seeing this with all our Xamarin Forms apps and have replicated with the latest XF stable release. The exception thrown is:

Objective-C exception thrown. Name: NSInvalidArgumentException Reason: -[AppDelegate xamarinSetGCHandle:flags:]: unrecognized selector sent to instance 0x282f85740

And is being thrown in Xamarin.Forms.Platform.iOS.FormsApplicationDelegate.

To replicate, install the Xamarin app on iOS 15 and run it, it should work.
Kill the app and run it again, it will immediately crash.
Workaround 1: Delete and reinstall the app (yuck)
Workaround 2: Reboot the device (slightly less yuck)

Easy to replicate in the debugger.

UPDATED:
Further information, I believe this is an issue with Xamarin.iOS bindings, not specifically an issue with Xamarin.Forms.

Can someone at MS at least acknowledge this? That you are aware? It is hard enough defending Xamarin right now without not being able to confirm this is being investigated.

More info for anyone watching this thread. Setting the deployment target to 14.0 resolved the issue for us, hopefully that won't be actually required before iOS 15 is officially released. See this thread:

xamarin/xamarin-macios#12427

Yet more info, enabling LLVM also solved the problem for us without having to modify the deployment target.
We did however have problems with LLVM in the past (years back). Hopefully those issues have now all been resolved.

As pointed out this seems more of a Xamarin.iOS problem and even more so: I have noticed apps that crash at startup (even Twitter) so it seems something that is happening in iOS itself. The Twitter app started working again after an iOS update (beta 7) I hope that was the case for this one as well.
