Xamarin.iOS project not running after xcode 11 update

I got following error message:

SyscallError: setpriority(PRIO_DARWIN_ROLE, 412, 3): No such process

in the ios device log when trying to run my xamarin.ios project after updating to xcode 11.0 and the lastest Visual Studio for mac.

The reason why I updated xcode was because there was a xamarin.ios update that was incompatible with the xcode version I was using; 10.3

My application starts, it shows the splash and then just stops running/crashes.

Here's what I've tried:

Has anyone experienced this issue and found a solution? All assistance would be highly appreciated.

@CliftonSteenkamp I just stumbled across this while looking for something else; however, we recently had the exact same issue happen. I don't believe it was related to updating the SDK version; but the exact same line ended up in the comments of the line above. I can't see this happening to two people around the same time as being a coincidence. There may be more to what you're saying than a simple key press.

I should say the developer who this happened to did not update his version of Xamarin. I updated mine and to Xcode 11+; but he did not. So it could still be related.

After days of investigation, trial-and-error and even updating my macOS to Catalina, I found the issue. Surprisingly it was something small and stupid(one line of code), would have honestly never thought of it. Anyway the issue was a line of code in my Main.cs that I somehow moved up to a commented line, perhaps I was clearing some line breaks.

This is what my Main.cs looked like:

public class Application
    {
        // This is the main entry point of the application.
        static void Main(string[] args)
        {
            // if you want to use a different Application Delegate class from "AppDelegate
            //you can specify it here. UIApplication.Main(args, null, "AppDelegate");
        }
    }

This is obviously what it was supposed to look like:

public class Application
    {
        // This is the main entry point of the application.
        static void Main(string[] args)
        {
            // if you want to use a different Application Delegate class from "AppDelegate
            //you can specify it here.
            UIApplication.Main(args, null, "AppDelegate");
        }
    }

The entry into my application had basically been commented out.

I apologise for wasting your time @LucasZhang-MSFT, regardless of that, I appreciate all your efforts.
