Bulk update failed
Library UI shows library.errors.bulkUpdateFailed when a multi-select update fails.
Why this happens
Network/API error, partial permission failure, or stale selection (files already moved/deleted). Distinct from single-item errors with clearer messages.
Diagnose and fix
1. Refresh My Files library (browse, search, sort); re-select items; retry.
2. Try the action on one file to surface a specific error.
3. Confirm you still own the files and they are not locked.
4. See A file or folder with that name already exists here if renaming/moving collides.
