I had the same issue, but it looks like the chat wasn’t actually lost — it was just loading very slowly.

What happened in my case:

• When I clicked the conversation in the Codex panel, it opened as empty (just like reported here).
• Then I went to the Chat tab instead of Codex.
• When I selected the same conversation there, it opened as a tab at the top (like a file) instead of in the right sidebar.
• In this view, the chat loaded instantly.

Meanwhile, the same conversation in the right sidebar was still empty, but after a few minutes, it eventually loaded there as well.

So it seems like the issue is related to how the chat is rendered in the sidebar vs. when opened as a tab.

Hi, I wonder how can I open a chat in the chat tab you mentioned?

Same issue in Cursor. Chat not loading from history.

Same issue for me when I use code VScode extentions. I think this issue didn't happend on me in the past. Any idea to fix?

Some sessions load at a glacial rate (minutes–hours). It often says "Loading model" for a bit, too, though even once the model "loads", the screen stays blank for quite some time.

Switching to certain chats (even if the chat has a much longer history) is instantaneous:

Same. I wonder is it a new problem after the latest update?
