failed to check context: %w

Error message

failed to check context: %w

What it means

Wrapper error in deleteContext: kc.ContextExists(name) failed while scanning the loaded kubeconfig files for the context entry. The existence check itself errored (not a simple 'does not exist'); cause is wrapped with %w and deletion aborts.
