codex - 💡(How to fix) Fix [Urgent] Codex Desktop project chat histories disappeared after recent update [6 comments, 5 participants]

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

26.429.30905 (2345)

What subscription do you have?

ChatGPT Pro

What platform is your computer?

macOS Tahoe 26.4.1 MacBook Pro 16-inch, Apple M5 Max, 128 GB memory

What issue are you seeing?

After what appears to be a recent Codex Desktop update today, almost all of my project chat histories disappeared from the sidebar.

The projects themselves are still listed, but most of them now show No chats. Only one main project still shows its previous conversation history. Before the update/restart, those other projects had existing conversation history.

This looks like a local history/indexing or migration issue rather than an intentional project deletion, because the project entries still exist while their associated conversations are missing from the UI.

Observed sidebar state from my screenshot:

• GGame still shows recent conversations
• CloudKitAdminPlatform shows No chats
• RaspberryPi shows No chats
• weighted-wheel shows No chats
• WAN Project shows No chats
• CodexAutoSwitcher shows No chats
• regular Chats also shows No chats

This is high impact because those missing project conversations contain important development context and task history.

What steps can reproduce the bug?

I do not yet have a deterministic repro, but this is what happened:

1. Use Codex Desktop with multiple projects that already have chat history.
2. Receive/apply the recent Codex Desktop update, or reopen Codex after the update.
3. Open Codex Desktop again.
4. Check the left sidebar project list.
5. Observe that most projects are still present but their chat histories are gone / shown as No chats.
6. Only one main project still shows previous conversations.

What is the expected behavior?

All existing project conversations should remain visible and searchable after a Codex Desktop update or app restart.

Specifically:

• Updating/restarting Codex should not hide or remove project chat histories.
• Existing projects should continue to show their associated conversations.
• If this is an indexing problem, there should be a safe way to re-index/recover the local project conversations.

Additional information

I have screenshots showing:

1. The sidebar state where only one project still has conversations while the other projects show No chats.
2. The Codex Desktop About dialog showing version 26.429.30905 (2345).
3. The macOS system information showing macOS Tahoe 26.4.1 and MacBook Pro Apple M5 Max.

Please investigate whether this is a UI/sidebar indexing bug, local migration issue, or possible data-loss problem. Also, please advise whether there is a safe recovery/re-indexing procedure for the missing project conversations.

Possibly related to prior local-thread/sidebar visibility issues, but this report is for Codex Desktop on macOS and affects project-level chat history after the latest update/restart.
