[BUG] "Failed to load session"

Preflight Checklist

• [x] I have searched existing issues and this hasn't been reported yet
• [x] This is a single bug report (please file separate reports for different bugs)
• [x] I am using the latest version of Claude Code

What's Wrong?

Claude Code tab in the Claude Mac desktop app fails to load sessions and hangs indefinitely. All previous chat history has disappeared after logging out and deleting the app and reinstalling and logging back in.

• Code tab showed "Failed to load" on existing sessions or hangs on "Contemplating..." when starting a new session
• All previous Code session history has disappeared after re-login
• Regular chat tab works perfectly fine

Environment Info

• Platform: macOS (Mac desktop app)
• Date issue started: ~February 13, 2026
• Note: Status page showed elevated errors on Opus 4.6, Sonnet 4.5, and Opus 4.6 Fast Mode around the same time. Issue persists despite status page now showing "Operational."

Additional Context

I had a substantial amount of work and session history built up over the past week. The session history loss occurred after logging out and back in while attempting to resolve the loading issue. This is particularly concerning as the chat interface itself suggested using /bug or /doctor to report issues, which is impossible when Code won't respond.

What Should Happen?

I should be able to talk in the sessions without an error.
