Bug: Threads missing at every single start of codex

Codex
1

I am using version 26.313.41514 on Windows 11. Since today (March 18, 2026), all threads have disappeared from the sidebar. The issue affects threads in two different projects.

The PC was restarted between March 17 and March 18, but no updates were installed during that time.

I asked Codex to recover the sessions, and they are still present in the directory .codex/session/yyyy/mm/dd. Codex attempted a recovery, but after restarting the program, the restored threads disappeared again.

I have no idea what to do.

Hi and welcome to the community!

I recently saw something similar while demoing the app to a friend. After a restart, the conversations were gone.

Other than my experience that some issues sometimes disappear after an update rolls out, I can only speculate about what is causing this.

Are you perhaps using the WSL agent environment? That can be changed in the general settings. Another possibility is that the ChatGPT account is not properly connected at the moment.

Hi. No, I don’t use the WSL. And I tried a clean new install of the app. But after closing and reopening, all threads are gone—every time.

Same here, on Linux.
Computer crash, lost all my thread but one, App, CLI and VS ext.
Not fun.

Even though all the filter options won’t repopulate the thread sessions in the sidebar, the search function still works.

It’s no longer an immediate blocker for me and maybe that will help someone else.

Sorry for the slow reply. Thanks for sharing that Search still finds the chats — that may help anyone with an empty sidebar. Current search and archive guidance is here: https://learn.chatgpt.com/docs/projects . If it still happens after restarting, please share your current app version and OS with Support so the persistence issue can be checked.
