Windows ARM64 Codex Desktop frequently exits/restarts while using a WSL workspace

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

Codex Desktop 26.715.4045.0 (native ARM64 package)

Bundled command runner observed: 0.145.0-alpha.18

What subscription do you have?

Not included in this report.

What platform is your computer?

• Windows 11, version 25H2
• OS build 26200
• ARM64
• Codex package architecture: ARM64

What issue are you seeing?

Codex Desktop frequently exits or restarts unexpectedly on Windows ARM64 during normal use. In one observed period, the desktop logs show several separate app process/session IDs within only a few minutes, consistent with repeated exits and relaunches.

The issue has been observed while a repository opened through a WSL UNC path was active. The logs contain a large number of repeated Git metadata warnings:

Failed to resolve git root: fatal: detected dubious ownership in repository at '//wsl.localhost/<distro>/home/<user>/<repo>'

These warnings are emitted repeatedly by git-origin-and-roots, electron-message-handler, and worktree environment setup. They may be unrelated, so this report does not claim they are the crash root cause. The desktop logs inspected did not contain an explicit native crash signature, access violation, or useful fatal exception immediately before exit.

What steps can reproduce the bug?

The crash is intermittent rather than deterministic:

1. Run the native ARM64 Codex Desktop app on Windows ARM64.
2. Open a Git repository through a WSL UNC path such as \\wsl.localhost\<distro>\home\<user>\<repo>.
3. Use Codex normally, including opening or switching tasks/workspaces.
4. The desktop app intermittently closes or restarts.
5. Relaunching allows work to continue, but the problem recurs frequently.

What is the expected behavior?

Codex Desktop should remain running during normal use. Git ownership or workspace metadata errors should be handled as recoverable workspace errors and should not destabilize the desktop process.

Additional information

• Multiple Codex Desktop log pairs with different process/session IDs were created within several minutes.
• Current native executable path confirms the ARM64 package: OpenAI.Codex_26.715.4045.0_arm64__2p2nqsd0c76g0.
• A previous app build (26.715.3651.0) also appears in nearby logs, suggesting the behavior may span an update.
• No dump file was found in the package data paths searched.
• Local usernames, repository names, session IDs, and full logs are intentionally redacted.

If maintainers can point to the preferred crash-dump or ETW collection procedure for the Store/AppX ARM64 build, I can provide a more diagnostic trace.
