Solutions

1. Check the main-process log for the underlying storage error
2. Restore or delete the corrupted store file (it is usually under userData) to let the app recreate it
3. Verify write permissions and disk space for the userData directory
4. Export/back up favorites before resetting storage

const isFavoriteStorageError = (e: unknown): e is FavoriteStorageError => e instanceof FavoriteStorageError;

try { await mgr.getFavorites(); } catch (e) { if (isFavoriteStorageError(e)) { return cachedFavorites ?? []; } throw e; }

When it happens

Trigger: Any proxy call when the main process cannot read/write its favorites store: disk I/O error, corrupted store file, locked file, or failed migration.

Common situations: Store file corrupted after crash; antivirus/permissions blocking the userData dir; disk full; concurrent Electron instances locking storage.
