Failed to launch browser Exception, occuring on specific computers

[janispa]

Hi,

we have a problem with starting Microsoft Edge (it works with Chrome though!) on some specific computers within our company. We tried to run the problematic code in the Console-Application and the Error still occurs. Console-Application code:

// See https://aka.ms/new-console-template for more information
using PuppeteerSharp;

    try
    {
        var browser = await Puppeteer.LaunchAsync(new LaunchOptions
        {
            Args = new[] { "--headless=new" },
            Headless = true,
            Devtools = false,
            HeadlessMode = HeadlessMode.True,
            ExecutablePath = "C:\\Program Files (x86)\\Microsoft\\Edge\\Application\\msedge.exe"
        });

        if (browser != null)
        {
            Console.WriteLine("browser is not null");
        }
    }
    catch (Exception ex)
    {
        Console.WriteLine(ex.ToString());
    }

This error is probably occurred by some local settings of the computers we working on (not all team members experience the same problem), but we can't figure out what can be the factor here.

Has anyone of your experienced anything similar?

As soon as we change the ExecutablePath to Chrome - it starts working.

Our configuration:

Windows 11 22H2 (Build 22621.4751)
Microsoft Edge Version 133.0.3065.69 (Offizielles Build) (64-Bit)
Console Application utilizes .Net 8
Visual Studio Runs in Admin mode
Alternative path to Chrome leads to: "C:\Program Files\Google\Chrome\Application\chrome.exe"

As a side note - even though the Console application raises an exception - the msedge process is successfully started and visible in Task Manager!

Can you share the InnerException?

It's null:
