@etraut-openai this seems to keep getting flagged as a dupe but seems to be an unresolved issue with the vscode extension. I am running into the same issue. Have tried deleting .codex and reinstalling the vscode extension. If I click "open Config.toml" it opens a blank .toml file. Before I click the button, no Config.toml exists at %USERPROFILE%/.codex
@CodySig, can you provide more details? Are you running on Windows? If so, with or without WSL?
Please check out our Windows troubleshooting tips to see if they address your problem.
Apologies for the lack of context. I am running VScode 1.107.1 on Windows 11. I am not using WSL.
Codex extension:

I am running locally in chat mode using gpt-5.2-codex with medium thinking. I ask it to help me scope a task, answer some follow up questions with a request for it to help me do some research which then requires network access. I allow it network access for the session then it crashes. I can consistently reproduce the issue each time I delete .codex and re-install the extension, so it doesn't seem to be session specific.

@CodySig, thanks for the additional details. Very helpful. Do you have the experimental Windows sandbox enabled?
When the crash occurs, open the "Output" panel in VS Code (or Cursor) and choose Codex. See if there's any additional log output that might help us determine the cause. Then restart the extension by choosing "Restart Extension Host" from the command palette. Once the extension is running again, issue a simple prompt like "Hi", and then use the "/feedback" command to upload your logs, and post the thread ID here. That will allow me to look at the debug information logged by Codex.
Huh, I re-installed again today once I got back to working on this (after about 11 hours), and it seems to be working completely fine now. I lost my session information because I had permanently deleted the .codex file, but it's working again. I tried this probably 10 times over a few hours before coming to this issue and was able to re-produce it every time. I guess I will just be on the lookout for it happening again. I appreciate the quick response and debugging steps. I will keep that in mind in the future.
