New Thread button does not open the new conversation on Windows

Codex Windows desktop client has a bug with the New Thread button.

Expected behavior:
Clicking New Thread should create a new conversation and immediately navigate to it.

Actual behavior:
From the UI, the button appears non-functional. However, logs show that thread creation succeeds, but the desktop UI does not open or render the new thread.

Environment:

  • Product: Codex Windows desktop client
  • Version: OpenAI.Codex 26.409.7971.0
  • App-server / CLI version: 0.119.0-alpha.28
  • Platform: Windows

What I already tried:

  • Repair
  • Reset
  • Uninstall and reinstall

Result:
The issue still persists after reinstall.

Relevant logs:

  • 2026-04-15 08:38:37: thread/start returned successfully
  • 2026-04-15 08:39:24: Conversation created

Conclusion:
Backend thread creation succeeds, but the Windows desktop frontend does not correctly navigate to or render the new thread.

Hey @Izuna, you’re not alone on this one, it’s been coming up in the “Error in starting conversation” thread too.

Totally get how blocking that is when the New Thread button just doesn’t respond.

Good news is this is already being worked on. It’s a known issue on Windows and the fix is in progress, so you shouldn’t need to change anything on your end.

In the meantime, a couple workarounds people mentioned:

  • Refreshing the page
  • Using the sidebar “New chat” if it responds
  • Restarting the browser session

Not ideal, but it can get you unstuck for now.

We’re watching that thread closely and should see this resolved soon. If you notice any pattern (browser, timing, etc.), drop it in the ongoing thread, it helps connect the dots faster.
