What version of the Codex App are you using (From “About Codex” dialog)?

OpenAI.Codex 26.730.8199.

What subscription do you have?

ChatGPT Pro

What platform is your computer?

Windows 10 Pro 22H2 (build 19045), x64. Remote Desktop session; Microsoft Remote Display Adapter.

What issue are you seeing?

## Summary
After updating the Microsoft Store ChatGPT/Codex app, it launches briefly and then exits without showing a usable window.

## Actual behavior
The app starts, the tray icon appears briefly, then disappears. No usable window remains open.

The app log shows successful app-server initialization:

```text
Current reported app-server version: 0.147.0-alpha.1.2
initialize_handshake_result outcome=success
Codex CLI initialized

It then stops before any renderer/window is created.

AppModel Runtime records package launch and subsequent AppX container destruction (event IDs 210, 211, 201, 217), without an actionable Application Error crash entry.

Troubleshooting already performed

Closed all ChatGPT/Codex processes
Signed out and created a completely new RDP session
Cleared and backed up app cache and local state
Re-registered the MSIX package
Uninstalled and reinstalled from Microsoft Store
Tested launch with GPU disabled
Confirmed the package status is OK

None of these steps changed the behavior.

Related report

This appears very similar to https://github.com/openai/codex/issues/28035

Request

Please confirm whether this is a known regression affecting the Windows 10/RDP desktop app and provide a supported workaround or fix.


### What steps can reproduce the bug?

1. Connect to the Windows 10 Pro 22H2 machine through Remote Desktop.
2. Install or update ChatGPT/Codex from Microsoft Store.
3. Launch ChatGPT from the Start menu.
4. The tray icon appears briefly, then disappears and no usable window remains open.
5. Repeat after clearing app data, reinstalling the Microsoft Store package, and signing out/in to a new RDP session: same result.

### What is the expected behavior?

ChatGPT/Codex should open and keep a usable window visible, reaching the sign-in or main application screen.

### Additional information

The issue occurs before opening a project or starting a task. No sensitive project data or credentials are included in this report.

Thanks. I reviewed #36084, but I don't believe #37105 should be closed
as a duplicate at this point.

There are several material differences:

#37105 occurs on Windows 10 22H2 build 19045 through a native RDP

session using Microsoft Remote Display Adapter.

#36084 occurred on Windows 11 build 26200 with a Parsec Virtual

Display Adapter.

#37105 affects OpenAI.Codex 26.730.8199, whereas #36084 affected

26.721.11231.0.

#36084 reported a specific Crashpad signature: two renderer 0xC0000005

crashes, a browser-process crash in chrome.dll, and ERR_FAILED while
loading app://-/index.html.

#37105 does not currently show that same crash signature. App-server

initialization succeeds, followed by AppX container teardown before a
usable renderer/window remains.

The issue persists after cache/local-state cleanup, package

re-registration, Store reinstall, GPU-disabled launch, and creation of a
new RDP session.

The visible symptom is similar, but the OS version, display environment,
app version, and available failure evidence differ. They may be related
regressions, but please keep #37105 open, or mark the issues as related,
until the same root cause is confirmed.
