codex - 💡(How to fix) Fix Windows 26.527.3686.0: enabling notifications triggers Electron app launch error with ?type=click&tag deep link

Error launching app

Unable to find Electron app at C:\Program Files\WindowsApps\OpenAI.Codex_26.527...\?type=click&tag=...

Cannot find module 'C:\Program Files\WindowsApps\OpenAI.Codex_26.527...\?type=click&tag=...'

### What steps can reproduce the bug?

1. Install or update Codex Desktop for Windows to `26.527.3686.0`.
2. Open Codex normally from the Windows Start menu.
3. Enable Windows notifications for Codex in Windows Settings.
4. The error dialog appears reliably after enabling notifications / notification handling is triggered.

I also tested the following:

- Disabling Windows mobile device access / phone connection did not fully resolve the issue.
- Closing Codex and killing stale `Codex.exe` / `codex.exe` processes reduced process accumulation, but the error still returns when Codex notifications are enabled.
- Keeping Codex notifications disabled prevents the error from appearing.
- Opening Codex from the Start menu works normally.

The error dialog includes a deep-link-like query string:

```text
?type=click&tag=...
Example error:
Error launching app

Unable to find Electron app at C:\Program Files\WindowsApps\OpenAI.Codex_26.527...\?type=click&tag=7051289366197316927

Cannot find module 'C:\Program Files\WindowsApps\OpenAI.Codex_26.527...\?type=click&tag=7051289366197316927'

### What is the expected behavior?

Codex should handle ?type=click&tag=... as a notification/deep-link argument, not append it to the Electron app path.
