Codex Windows desktop app crashes on startup: app-server websocket closed code=3221225781

Codex Windows desktop app crashes immediately after opening.

Error shown:
(code=3221225781, signal=null)
Most recent error: Codex app-server websocket closed (code=3221225781)

What happens:

• I install/open Codex on Windows.
• The app checks for updates and says the latest version is installed.
• Immediately after that, this error screen appears.
• Reload does not fix it.
• Check for updates does not fix it.
• Open Config.toml does nothing.
• I manually checked C:\Users\DeAnno\.codex.
• There was no config.toml originally.
• I tried creating config.toml with Windows sandbox settings, but the same error happened.
• I also tried Repair/Reset from Installed Apps, but the crash still happens.
• There is no sandbox.log file, so it may be crashing before sandbox startup.

Environment:

• Windows 11 Pro
• Codex installed from Microsoft Store
• Using Codex desktop app, not VS Code
