### Bug Description

i installed fresh strapi@latest, which is strapi v5.9.0, then i installed, "@strapi/plugin-graphql": "^5.9.0", 
then, on https://localhost:1337/graphql i see on page that:
______________ERROR________________________________________
Schema Introspection Failure
The introspection query failed. Please reload and try again.
______________________________________________________________

Q: why i install graphql plugin without any content type 
A: because  previously  I have content-type then install graphql then i see same error so, i thought, this is seeing because of complex content type or components types,

what i thought:
as this happen in fresh strapi install error might in
1. strapi v5.9.0 it self with some dependencies or
2. with any configuration which i need to configure after installing strapi and graphql plugin, 



### Steps to Reproduce

steps to reproduce:
1.  install strapi@latest (5.9.0) -- COMMAND: npx create-strapi@latest
     1. i installed with typescript ( in strapi options)
2. install graphql plugin(5.9.0) --COMMAND: npm install @strapi/plugin-graphql
3. open http://localhost:1337/graphql

seen error:
Schema Introspection Failure
The introspection query failed. Please reload and try again.

### Expected Behavior

http://localhost:1337/graphql should not give introspection error

### Logs
