What's included

  • App closes within seconds of every launch, crash in CrBrowserMain inside Codex Framework, sometimes with V8 out-of-memory logs
  • Launch crash tied to a large custom pets catalog in the Codex home folder; moving the folder restores startup
  • Whole app closes without an error message after minutes of agent work in a project
  • Opening or restoring a chat that has a large PDF preview tab terminates the app
  • Repeated Chrome_IOThread SIGTRAP crashes during long tasks, computer-use QA or chat switching, alongside sluggish navigation

Not included

  • Errors shown inside the app while the app stays open
  • Codex Web or standalone CLI failures
  • Push notification registration warnings at startup that do not end the process
