No admin panel after installing graphql plugin

Hi everyone, I am new to strapi and I noticed that as soon as I install graphql(npm run strapi install graphql) plugin into my newly create strapi project (npx create-strapi-app name),

The admin panel altogether goes away and never comes back. I tried uninstalling the plugin, even then the admin panel is lost and I am not able to make any change at all.

Please let me know if I am missing something and how should I resolve this issue.
Thank you so much.
