Hello OpenAI team,
I believe I have encountered a serious bug in the latest Windows ChatGPT Work desktop application.
Environment:
- Windows 11
- Latest ChatGPT Work desktop app (Microsoft Store version)
- ChatGPT Plus
- Google Sign-in
Issue:
After updating to the latest ChatGPT Work desktop app, every Project became unusable.
The web version (chatgpt.com) works perfectly:
- Chats are normal
- Projects are normal
- Conversation history is intact
- Same account
Only the Windows desktop app is affected.
Symptoms:
- Every Project shows a long Base64-like string instead of the assistant response.
- Even a brand-new Project immediately breaks after sending a simple message like “Hello”.
- Every response ends with:
“user not found, 用户不存在”
- A red error icon appears beside every Project.
- Project memory never loads.
- The desktop app becomes unusable for Projects.
Troubleshooting already attempted:
- Restarted Windows
- Logged out and logged back in
- Reinstalled the desktop application
- Reset application data
- Verified that the web version works correctly
- Verified that the issue affects every Project, including newly created ones
Important observations:
- This problem only exists in the Windows desktop app.
- The web version is completely normal.
- Therefore the cloud data appears intact.
- It seems the desktop client is incorrectly parsing the server response instead of rendering it.
One additional observation:
The displayed content starts with a JWT/Base64-looking payload (beginning with “eyJ…”) and eventually ends with:
“user not found, 用户不存在”
This appears to be an internal response that is accidentally rendered directly to the UI instead of being processed.
I have attached screenshots demonstrating the issue.
Please investigate whether this is related to the recent ChatGPT Work / Codex desktop update.
Thank you.
