Previous work sessions with mapped project folders disappear from the sessions list

## Bug: Previous work sessions no longer appear (with mapped project folders)

### Description
I had approximately 3 previous work sessions in Claude Code (desktop app), each with a mapped project folder and files generated during the work. Today (2026-09-14) I noticed these sessions no longer appear in the app.

### Expected behavior
The previous sessions, with their project folders and history, should remain visible and accessible in the sessions list/sidebar.

### Actual behavior
Only 1 session besides the current one is returned when listing sessions (including archived ones). The ~3 work sessions with mapped project folders do not appear anywhere.

### Steps to reproduce
I did not identify any action that caused the issue — no app update, account switch, or manual cleanup was done recently. The disappearance was only noticed today, when trying to resume the work.

### Environment
- OS: Windows 11 Home Single Language
- App: Claude Code (desktop app)

### Impact
Loss of access to work sessions with generated files and associated project context.
