Keystone 16.0.0 Error: Cannot use GraphQLSchema "[object GraphQLSchema]" from another module or realm

See original GitHub issue

Bug report

Describe the bug

I get the following error after bumping @keystonejs/keystone to ^16.0.0:

Error: Cannot use GraphQLSchema "[object GraphQLSchema]" from another module or realm.

Ensure that there is only one instance of "graphql" in the node_modules
directory. If different versions of "graphql" are the dependencies of other
relied on modules, use "resolutions" to ensure only one version is installed.

https://yarnpkg.com/en/docs/selective-version-resolutions

Duplicate "graphql" modules cannot be used at the same time since different
versions may have different capabilities and behavior. The data from one
version used in the function from another could produce confusing and
spurious results.

  },

Deleting ./node_modules/@keystonejs/keystone/node_modules/graphql allows the app to build and start 🤷‍♂️
