What's Wrong?

Title: Sidebar sessions list empty across all projects (desktop app)

Environment: Claude desktop app on macOS, version 1.19367.0 → reproduced through update to 1.20186.0. CCD (claude-code) bundle 2.1.202 → 2.1.205.

Description:
All sessions disappeared from the left-hand sidebar across every project. Confirmed this is not data loss — 64 local session files remain intact under ~/Library/Application Support/Claude/claude-code-sessions/<account>/<workspace>/ and under ~/.claude/projects/*/.

Tried, no effect on the sidebar:

Restarting the app (3x)
Clearing Chromium render caches (Cache, Code Cache, GPUCache, Dawn caches)
Clearing IndexedDB, Local Storage, Session Storage under the app's user-data dir, then relaunching
Related crash observed during troubleshooting (may or may not be connected): app got stuck on a "Downloading update…" spinner indefinitely. ~/Library/Logs/Claude/claude.ai-web.log showed:

[spa] chunk preload failed; running diagnostics, then reloading
TypeError: Failed to fetch dynamically imported module: .../cf683581d-B_eeRwrN.js
[BOOTSTRAP] Fatal error boundary triggered {"errorCode":"1XAF0WC","url":"/upgrade"}
A full quit/relaunch cleared that spinner and the app updated cleanly, but the sidebar stayed empty afterward.

Diagnostic note: ~/Library/Logs/Claude/main.log shows the LocalSessions component logging setFocusedSession for the single currently-open session, but never logs any session-listing/enumeration call — suggesting the sidebar's fetch of the full session list isn't firing, despite the underlying local session files being present and valid.
