You are welcome to discuss Codex issues on the forum, however the official place to report and track them is the GitHub issue tracker for OpenAI Codex.

I had ChatGPT look for the closest related issue and it identified:

If that issue matches your problem, consider adding a :+1: reaction on the GitHub issue page itself, not just on the forum topic, as reactions on GitHub help the developers gauge impact and prioritize work. Since there are also many other issues like it, give each issue that seems close a :+1: reaction to help the developers gauge impact and prioritize work.

If it is not the same issue, try searching the existing GitHub issues for a closer match. If you cannot find one, then open a new issue with as much detail as possible.
