}What issue are you seeing?
When I suspend my codex session with ^Z and then resume the codex session, codex appears to be hung. It shows a prompt and I can type into it, but when I hit enter, nothing happens. No "working...", no "press esc to interrupt", just nothing. Esc has no effect. I used to be able to resume codex sessions with no issue.
What steps can reproduce the bug?
Uploaded thread: 019ee1f8-d900-7bb3-b250-d10f8e1680b5
What is the expected behavior?
Codex resumes accepting prompts on resume.
