[Bug]: Microsoft Edge (ARM64) closes immediately in Playwright headless mode when Azure DevOps agent runs as a Windows service

Nobody has claimed this yet.

### Version

1.60.0

### Steps to reproduce

1. Set up a Windows 11 ARM64 machine with a self‑hosted Azure DevOps agent.
2. Install Microsoft Edge ARM64 and Playwright.
3. Configure the Azure DevOps agent to run as a Windows service.
4. Run any Playwright test using `msedge` in headless mode.
5. Observe that Edge launches and then immediately exits with no error.
6. Stop the service and run the Azure DevOps agent interactively in a user session.
7. Run the same test again — it now works normally.

### Expected behavior

Playwright should be able to launch Microsoft Edge (ARM64) in headless mode consistently, regardless of whether the Azure DevOps agent is running interactively or as a Windows service (Session 0). The browser should remain running long enough for tests to execute.

### Actual behavior

When the Azure DevOps agent runs as a Windows service:

- Edge ARM64 starts
- Immediately exits
- Playwright reports that the browser closed unexpectedly
- No tests run
- No meaningful error message is produced

When the agent runs interactively, everything works correctly.

### Additional context

- This is a brand‑new ARM64 laptop, so it has never run the old Chromium/Edge headless mode.
- The failure occurs in headless mode, not headful.
- The only difference between working and failing is interactive session vs Windows service.
- This suggests a possible interaction between:
- Edge ARM64
- Playwright’s newer “real browser” headless mode
- Windows Session 0 restrictions
- There are similar issues for x64 Chromium/Edge in CI, but none that match:
- ARM64
- Edge ARM64
- Azure DevOps agent as a service
- Headless mode
- Browser exiting immediately

### Environment

```shell
- Playwright version: (1.60.0)
- Browser: Microsoft Edge ARM64
- OS: Windows 11 ARM64
- Azure DevOps agent: Self‑hosted, running as a Windows service
- Execution mode: Headless
- Hardware: New ARM64 laptop
```

Reproduce the failure on Windows 11 ARM64 with Microsoft Edge ARM64 and Playwright 1.60.0, comparing an Azure DevOps agent running as a Windows service with an interactive session. Investigate the headless launch behavior in Session 0 and capture a meaningful failure signal. Done means Edge remains running and Playwright tests execute successfully in the service configuration.
