What issue are you seeing?

Codex worked normally this morning but suddenly stopped allowing new conversations this afternoon.
Existing conversations work normally.
New conversations fail in both existing and new projects.
Error: "Couldn't load workspace settings."
Clicking Retry fails almost instantly (within 0.5 seconds).
Profile avatar unexpectedly changed from orange to blue.
Profile information can no longer be accessed.
ChatGPT web version works normally.
Troubleshooting attempted:
Signed out and back in.
Restarted Codex and Windows.
Terminated all related processes.
Checked network connectivity.
Tried multiple projects and new conversations.
None of these resolved the issue.
Expected behavior: New conversations should start normally.
Actual behavior: All new conversations are blocked. Only previously initialized conversations remain functional.
Please investigate and fix this urgently. This issue completely prevents starting new work in Codex.
