Hey, Renu353. There could be more than one possible issues for this problem. I have listed below some solutions.

  1. Open your browser manually, clear cache and cookies, then run composer-playground
  2. If that doesn't work, try opening your browser from your command line. If you are not able to open it, re-install your browser
  3. If you are running composer-playground as root, try running it as non-root user (certain browsers do not allow you to open the browser if you are root).
  4. Re-install nodejs, composer, composer-playground.
