codex - 💡(How to fix) Fix Codex App on macOS crashes with SIGABRT after sending a message; earlier missing rollout path

## Summary

Codex App on macOS crashes after sending a message. Initially it failed to resume a local conversation because the expected rollout JSONL file did not exist. After reinstalling Codex App and clearing local Codex state, the app still crashes with `SIGABRT` / `thread caused non-unwinding panic`.

## Environment

- OS: macOS
- Architecture: [Apple Silicon / Intel]
- Codex App version: [paste version from About Codex]
- Install source: Codex App official download page
- Login method: ChatGPT account
- Workspace tested:
  - `/Users/<user>/Documents/Codex`
  - `/Users/<user>/codex-empty-test`
- Time of occurrence: 2026-05-08 around 12:30–12:41 local time
