failed to switch context: %w

Error message

failed to switch context: %w

What it means

Wrapper error in InteractiveSwitchOp.Run: switchContext(choice) failed after the user picked a context in fzf — the switch itself (kubeconfig parse, current-context write, save, previous-context recording) errored. The pick succeeded but applying it did not; cause wrapped with %w.

Solutions

1. Check the wrapped cause (commonly kubeconfig write/save failures)
2. Ensure the kubeconfig file is writable and retry
