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

Version: 26.707.72221 - Released: Jul 14, 2026

What subscription do you have?

ChatGPT Plus

What platform is your computer?

macOS 26.5.2 (25F84)

What issue are you seeing?

Every new Codex task fails immediately with:

Error creating task
no rollout found for thread id ...

This happens for every newly created task.

I have already tried:

  • Signing out and signing back in
  • Restarting ChatGPT Desktop
  • Creating multiple new threads
  • Verifying that Codex CLI works correctly on the same machine and account

The issue only affects the ChatGPT Desktop Codex UI. Codex CLI works normally.

Environment:

  • ChatGPT Desktop for macOS
  • Version: 26.707.72221 (Released Jul 14, 2026)
  • ChatGPT Plus

What steps can reproduce the bug?

  1. Open ChatGPT Desktop on macOS.
  2. Switch to Codex.
  3. Create a new Codex task.
  4. Enter any prompt (for example: "Reply with OK only.").
  5. Submit the task.

Result:
The task immediately fails with:

Error creating task
no rollout found for thread id ...

What is the expected behavior?

Every newly created Codex task immediately fails with:
"Error creating task"
"no rollout found for thread id ..."

I am experiencing the same issue.

Environment:

  • Windows desktop app
  • OpenAI.Codex version 26.707.9981.0
  • ChatGPT -> Codex automatic task handoff fails
  • Manual Codex tasks created directly in Codex app work correctly

Additional details:

  • Reinstall/repair/reset of the Windows app did not fix it.
  • The error persists when creating a new task from ChatGPT.
  • Multiple ChatGPT processes and a Codex process remain active after the failure.

Please let me know if additional logs are needed.

Windows reproduction with a narrower “phantom sidebar reference” variant.

Environment:

  • Codex Windows app 26.810.7004.0
  • bundled codex-cli 0.148.0-alpha.9
  • Windows 10.0.19045

Observed UI error:
Failed to resume chat — no rollout found for thread id 01a0085a-6853-73f1-b51d-55288dd018ef

Read-only local forensic classification for this exact ID:

  • no matching rollout filename under the normal sessions directory;
  • no matching rollout under archived sessions;
  • no exact ID in the local session index;
  • no exact ID in the current local thread/state databases;
  • the task nevertheless remained selectable from the Desktop sidebar.

This is not “every new task fails”; it is one persisted sidebar/server reference whose durable local rollout mapping/payload is absent. Restarting or repeatedly clicking Resume cannot reconstruct a file that is not present.

Requested product behavior:

  1. distinguish rollout-file-missing, db-index-missing, and remote-sidebar-reference-without-local-payload;
  2. offer a non-destructive reconciliation/re-index action when recovery is possible;
  3. quarantine or clearly mark an unrecoverable phantom entry instead of repeatedly attempting Resume;
  4. preserve all unrelated rollouts and never recommend deleting the whole local database/cache;
  5. surface a diagnostic bundle/feedback ID that contains only sanitized metadata.

No auth cache, credentials, private path, conversation content, or database file is attached.
