Codex doctor report

Now I've downgraded to 0.148.0 and continue my work, so it's not available.

What issue are you seeing?

After updating to 0.149.0, I tried to resume my previous work but encountered the error unexpected status 401 Unauthorized: error:{"Missing API key"}. I hadn't changed any Codex settings. I rolled back to 0.148.0, and then continued working as usual, and everything worked fine.

I logged in with echo $env:OPENAI_API_KEY | codex login --with-api-key.

Latest Codex Desktop also has this bug.

What steps can reproduce the bug?

1. Upgrade to 0.149.0
2. Run codex and continue a session
3. It shows unexpected status 401 Unauthorized and Missing API key error message.

What is the expected behavior?

Sessions should work normally.
