ERROR: An error occurred when writing to the output stream.

I have created a new empty iOS project and debugging of this project works on my iPad. It takes much less time to install this new empty iOS project on my iPad.

In addition, I have tested again my other bigger iOS project. It still always crashes a few seconds after the launch screen is displayed on my iPad. I found out that it even crashes when I set a breakpoint at the beginning of the code and a few seconds after the breakpoint got executed my game crashes. I have tried to set a breakpoint in different lines and it always crashes a few seconds after a breakpoint got executed. And when I set no breakpoints at the beginning then the game crashes too after a few seconds.

For example, I set a breakpoint in Program.cs in this line and the game crashes a few seconds after the breakpoint got executed. I did nothing when the breakpoint got executed, I just waited a few seconds until the game crashes.

 static void Main(string[] args)
 {
     UIApplication.Main(args, null, typeof(Program));
 }

I have tried to set the breakpoint in my new empty iOS project in the same line and I waited a few seconds after the breakpoint got executed and here the application crashes too.

Is it possible that my game crashes because it takes too long until my game is running on my iPad?

Program.cs:

using Foundation;
using System;
using UIKit;

namespace IOSTest
{
    [Register("AppDelegate")]
    internal class Program : UIApplicationDelegate
    {
        private static Game1 game;

        internal static void RunGame()
        {
            game = new Game1();
            game.Run();
        }

        static void Main(string[] args)
        {
            UIApplication.Main(args, null, typeof(Program));
        }

        public override void FinishedLaunching(UIApplication app)
        {
            RunGame();
        }
    }
}

iOS sample: https://easyupload.io/v0gb8a

I run the sample on my device(with iOS17.4, I don't have the device with the latest iOS version), it works.

Is it possible that my game crashes because it takes too long until my game is running on my iPad? Please check the device log of your iPad (Open VS, click the mobile icon behind the pairing to mac icon), then we can investigate further.

This log file is from the iOS sample project. The application crashes when I set a breakpoint in the line UIApplication.Main(args, null, typeof(Program)); and when I just wait a few seconds after the breakpoint is executed.

There is some sensitive private information in the log, such as IP, device id. To protect your security information, I have removed the log file.

From the log file, I can see you are using .net8.0.1. And there is a prompt saying "Installing workloads using rollback file".

I know you are using the latest VS, and the latest MAUI version is 8.0.70. Could you double-check the MAUI version?

I created a new .NET MAUI App and I have the same problem when I debug on my iPad.

After creating the new project the NuGet packages version 8.0.70 is not installed:

Then I updated the NuGet packages to version 8.0.70:

I don´t get an error when I debug on my iPad. But the application always get terminated a few seconds after a breakpoint got executed, maybe after 5-8 seconds.

I made a breakpoint here in Program.cs for testing:

 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, typeof(AppDelegate));
 }

What can I do so that I have more time to debug my application? I don´t want that the application gets automatically terminated after a breakpoint got executed.

Please open terminal in VS and run "dotnet workload install iOS" which will update the .NET-iOS workload of Visual Studio. Or try to install and use VS 2022 preview to see if the issue still exists.
