What's Wrong?

All recent sessions appear in the sidebar but open completely empty — no conversation history is visible. This affects every session except the currently active one.

Steps taken that did not fix it: restarted the app, checked for updates (already on latest), signed out and back in.

OS: Windows 11 Enterprise
App version: 1.7196.0 (desktop app)
Claude Code version: 2.1.138

What Should Happen?

Clicking a session in the sidebar should load and display the full conversation history.
