he Codex macOS app repeatedly crashes shortly after startup.

Crash reports show:

• Exception: EXC_BREAKPOINT
• Signal: SIGTRAP
• Termination: Trace/BPT trap: 5
• Faulting thread: CrBrowserMain
• App version: 26.616.81150
• Build: 4306
• macOS: 26.5.1 (25F80)
• Architecture: arm64

The app log contains:

```text
ERR_FAILED (-2) loading 'app://-/index.html'

Another log entry shows the bundled node version check failing:

nodeVersionStatus=failed
nodeVersionError={"code":null,"killed":true,"signal":"SIGTERM","cmd":"/Applications/Codex.app/Contents/Resources/
cua_node/bin/node --version","stdout":"","stderr":""}

The bundled Codex CLI runs:

/Applications/Codex.app/Contents/Resources/codex --version

Output:

codex-cli 0.142.0

But the app process itself crashes in Chromium/V8 startup code.

What steps can reproduce the bug?

  1. Open Codex.app on macOS.
  2. Wait for the app to start loading.
  3. The app crashes shortly after launch.

  This happened multiple times on 2026-06-25.

### What is the expected behavior?

Codex.app should launch normally and keep running.

### Additional information

I will attach the crash reports and app logs.

  Please note that the bundled CLI works, but the app UI/runtime crashes with `EXC_BREAKPOINT/SIGTRAP` in
  `CrBrowserMain`.

  I also see this warning when running the bundled CLI:

  ```text
  WARNING: proceeding, even though we could not create PATH aliases
