I have confirmed that all the logs still exist in the .codex directory.

It makes it literally unusable because i have to start a new session when i am working on the same project.

What steps can reproduce the bug?

Try resuming a chat in a remote vs code session.

What is the expected behavior?

That i can continue a previous chat in the same workspace/project.

I met the same problem as you, and it happened in cursor IDE too.

I had to install the cli version to even use it. The extension is basically unusable

[qwertyforce]

i have the same issue, i made the mistake of updating the chatgpt extension to the latest version, and now conversations don’t load.
reverted to 26.415.20818, and it works now.

Installed this version and it is still inconsistent in loading the chats. I don't know if it is a db error or something else, but this is the only coding extension that just doesn't work.

Have a look to my workaround here: #18993 (comment)

This worked initially, then it just went back to being slow at loading the conversation and then my codex cli became slow and it couldn't retrieve my old chat history. I just backed up my old .codex directory and deleted it for a fresh start. Luckily i was using it in one project, so much wasn't lost.

I am sticking to the codex cli for now, I haven't tried the extension since the reset. It just sucks because claude code extension works really well.

The only major difference i can see is that claude code only lets you continue a chat in a the workspace you started it like copilot chat, but codex allows you to open a previous chat anywhere. I wonder if this is the cause.

[ULudo]

I hit what looks like the same issue on the VS Code remote extension with Codex extension 26.422.30944.

Symptoms:

• Existing chat would spin forever / not load.
• Reloading the VS Code window did not help.
• Fully closing and reopening the remote VS Code connection did not help.
• The target session JSONL and Codex SQLite DBs were valid; a fresh codex app-server could read the thread successfully.

The extension log showed repeated startup overload around apps/connectors, including:

codex_app_server::transport: dropping overload response ... outbound queue is full
Server overloaded; retry later.
unsupported feature enablement `workspace_dependencies`
[IpcClient] Received broadcast but no handler is configured method=thread-stream-state-changed

Workaround that fixed it for me:

# ~/.codex/config.toml
[features]
apps = false
workspace_dependencies = false

Then reload/reconnect VS Code so the extension starts a fresh app-server.

This appears to disable the connector/apps startup path that was wedging the extension. It is a workaround, not a root-cause fix, and it may temporarily disable app/connectors and workspace dependency features.

[geniusadventurer]

The same problem. I used Codex VSCode extension in WSL Ubuntu 22.04. The version is 26.422.30944.

[TechaY]

I’m having the same problem too. I have to try several times without really understanding why it sometimes works.
