I am getting this using Xamarin Forms and deploying on an iPad Air (4th gen) on iOS 14.8.1. I develop using VS 2019 v 16.11.5. There is no Mac connected.

I get this output in this way: I request VS to deploy and run on the iPad. It does some stuff and eventually displays a message prompting me to start the app on the iPad. Shortly after I do that I get the bulk of these messages and the app dies.

Thanks for looking at this.
