Not Sure , Here is how i Fixed it.

"""

Fix the broken Codex Desktop session opening issue without touching the repo worktree.

Back up the affected Codex session files first. Then inspect the saved .jsonl session history and session_index.jsonl for malformed/raw subagent notification records, such as <subagent_notification> payloads or raw completed":"..."} JSON blobs that Codex Desktop may try to render.

Replace only those renderer-breaking records with safe plain-text equivalents, preserving valid session history wherever possible. Validate the JSONL after editing. If the sidebar still crashes or shows a stale title, clean the matching session index entry so there is only one valid title for the affected session.

Also scan recent session files across projects, because Codex Desktop’s global sidebar renderer may crash from malformed records in unrelated sessions. Do not modify any project repo files or worktree changes.
