Solutions

1. Inspect error.message (also preserved in details) for the underlying cause
2. Check main-process logs around the failing tag operation
3. Validate/back up the tag store if errors persist
4. Retry after restarting the app to clear transient locks

const isFavoriteTagError = (e: unknown): e is FavoriteTagError => e instanceof FavoriteTagError;

try { await mgr.updateTags(...); } catch (e) { if (isFavoriteTagError(e)) { await backoffRetry(once); return; } throw e; }

When it happens

Trigger: Any tag operation via the proxy where the main process throws an unexpected error while mutating tag storage.

Common situations: Storage-level failures during tag writes; partial state after interrupted operation; unexpected data shapes in tag store after migration.
