Netch fails to stop, stuck on "Stopping" after Windows 11 24H2 update

[IshanArdithya]

Describe the bug

After updating to Windows 11 24H2, when I try to stop Netch, it remains stuck on "Stopping" and never fully stops. The only way to close it is by ending it from Task Manager.

This issue started occurring only after the 24H2 update.

To Reproduce

1. Open Netch
2. Start the application
3. Attempt to stop the application

Log

Xray.log
application.log

Environment

OS: Windows 11 x64 Pro 24H2 26100.2605
Netch Version: 1.9.2

I face the same problem after updating to Windows 11 24H2.

Can someone fix it？

Tested this, and it does stop the tunnel, but it doesn’t proceed with the justification that it's ended. The current workaround is a force close via Task Manager. Suggest bumping this issue for further investigation.

I am also facing the same problem with Netch 1.9.7 + Win11 24H2 (1000.26100.48.0 )

I had the same issue, and now it won’t even start. If I start with LAN Bypass, it closes automatically. I'm trying to debug the situation. I think the app can't create a network interface on my PC, so it tries to find the interface 20 times before exiting the program after getting null.

Nekobox also took too long to connect TUN in Windows 11 (Version 24H2). Maybe need to try increasing these numbers

for (var i = 0; i < 100; i++)
{
    await Task.Delay(300);
    try
    {
        _tun.InterfaceIndex = NetworkInterfaceUtils.Get(ni => ni.Name.StartsWith(interfaceName)).GetIndex();
        break;
    }
    catch
    {
        // ignored
    }
}
