### Windows Version

Microsoft Windows [Version 10.0.26100.6584]

### WSL Version

2.6.1.0

### Are you using WSL 1 or WSL 2?

- [x] WSL 2
- [ ] WSL 1

### Kernel Version

6.6.87.2-1

### Distro Version

_No response_

### Other Software

_No response_

### Repro Steps

Occasionally, an error occurs when I try to start WSL. When it does occur, sometimes restarting `hns` fixes it, but more often I need to reboot. This can happen multiple times per day. Quite frustrating!

I always use the mirrored networking mode.

Note: I am aware of #12351, #12470, and #13454. Perhaps additional logs from me will help the team trace this down?

### Expected Behavior

No error on launch.

### Actual Behavior

```
wsl: An internal error occurred.
Error code: CreateInstance/CreateVm/ConfigureNetworking/0x8007054f
wsl: Failed to configure network (networkingMode Mirrored), falling back to networkingMode None.
```

Start with the WSL launch path named in the error, CreateInstance/CreateVm/ConfigureNetworking, and inspect the attached WslLogs and WslNetworkingLogs archives. Reproduce startup with networkingMode Mirrored, compare failures with cases where restarting hns or rebooting helps, and consider the issue done when launches no longer fall back to networkingMode None.
