That stderr is just Chrome trying to launch headful on a machine with no X server / no $DISPLAY.

First, please paste:

openclaw --version

If this is a VPS, SSH session, or otherwise headless Linux box, set the browser to headless in ~/.openclaw/openclaw.json:

{
  browser: { headless: true }
}

Then restart the gateway and retry openclaw browser start.
