ChatGPT Desktop Blocks New Work Threads After Major Bug Hits
On October 7, 2026, ChatGPT desktop users hit a wall. They could not start new Work threads. For many, this feature is essential. The problem came from a bug in version 26.1002.51308. OpenAI confirmed the issue and pushed out a fix fast. The update covered Linux, macOS, and Windows.
This was not a minor glitch. The outage affected everyone using the desktop app. OpenAI's incident page marked it as a partial outage for Codex in ChatGPT Desktop. Codex Web, CLI, VS Code extension, and Codex API kept running. The fault was on OpenAI's end. User setups were not to blame. The OpenAI status report called it "Elevated Work Mode errors." Both ChatGPT Work and Codex in the desktop app were hit. After the fix, all services came back online.
In the days leading up to the October 7 outage, OpenAI reported increased error rates across multiple products, including ChatGPT Work, image generation, Spaces, Pages, and API rehydration.
How the outage unfolded and was fixed
OpenAI first flagged the problem at 05:31 UTC. The company said, "We are investigating the issue. Version 26.1002.51308 is affected." By 05:54 UTC, they found the cause. They started rolling back to an earlier version. Linux and macOS users got the fixed app at 09:28 UTC. Windows users got it soon after. At 11:53 UTC, OpenAI announced, "We have released an updated app version with the fix for Linux, macOS and Windows. Affected users should update to the latest version."
The bug did not break all Work chat features. The OpenAI Codex public tracker showed that Windows users on version 26.1002.51308 could not send messages in new Work chats. Old chats still worked. This was not a total shutdown. It was a targeted failure.
The incident's title changed over time. It started as "new thread failed on the latest desktop app version for personal accounts." Later, it became "Unable to create new ChatGPT Work threads in latest version of desktop app." Some confusion remained about which accounts were hit. But the technical fact was clear. Anyone on version 26.1002.51308 could not start new Work threads in the desktop app.
Independent incident monitoring confirmed that on October 7, 2026, there were two separate disruptions: an earlier Workspace Agents outage lasting 1 hour and 49 minutes, and a distinct issue with Work thread creation in the desktop app.
What users need to do now
If you still cannot create Work threads, you are likely on the broken version. The fix is simple. Update the ChatGPT desktop app to the latest version. On Windows and Linux, open the app menu and choose "Check for Updates." On macOS, use the menu bar. After updating, quit and reopen the app. That should restore everything. If you cannot update right away, Codex is still available through the web, CLI, or VS Code extension.
OpenAI's status page now shows all systems working. The company also fixed two other incidents between October 5 and 7. One was a Workspace Agents issue. The other was Elevated Work Mode errors. This was a rough patch for ChatGPT's enterprise tools. For more on how repeated Work Mode problems have affected users, see this OpenAI incident summary.
Editorial perspective
OpenAI moved fast to fix the Work thread bug in ChatGPT Desktop. The episode shows how a single bad update can break workflows for thousands. Speed matters. So does clear communication. Users need to keep apps updated and watch official status pages when things go wrong. In AI desktop software, resilience is not optional. Neither is timely information.
