kubeconfig error: %w

Error message

kubeconfig error: %w

What it means

Generic kubeconfig parse guard inside switchContext: loading or decoding the kubeconfig files failed before the target context could be checked. Wrapped error indicates whether it was a load failure (unreadable/missing file) or a decode failure (invalid YAML).
