What's Wrong?

Description
All previous Claude Code sessions disappeared from the sidebar in the desktop app (Claude for Mac). Sessions were visible ~8 hours ago but are now gone. Only the current session appears.

The session files still exist on disk:

~/.claude/projects/-Users-***************
├── ***-...jsonl (Feb 8)
├── ***-...jsonl (Feb 9-10, ~36 MB)
├── **-...jsonl (Feb 10-12, ~54 MB)
└── ******-...jsonl (Feb 13, current)

What Should Happen?

Previous sessions should appear in the sidebar and be resumable

No .jsonl files were deleted — this appears to be a UI/indexing issue
