cmd start brave exited with status {status}

Error message

cmd start brave exited with status {status}

What it means

On Windows, open_in_brave invokes `cmd /C start brave <url>`; when the command completes with a non-zero exit status the status is reported. This means Windows could not resolve or launch the 'brave' app registration.
