Solutions

1. Inspect the wrapped message; if it mentions tag conversion, audit stored tag entries for malformed fields
2. Rebuild the tag library from favorites if corrupted
3. Verify storage provider health

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

try { return await manager.getTags(); } catch (e) { if (isFavoriteStorageError(e)) { return []; /* derive tags from favorites as fallback */ } throw e; }

When it happens

Trigger: storageProvider.getItem/updateData for TAGS failing; tag entries with unexpected shapes causing compare/convert functions to throw during sorting.

Common situations: Corrupted tag store after partial imports; custom or legacy tag data missing fields; provider read failures.
