Gatsby: Error `Failed to load config "react-app" to extend from.` after update to `2.17.10`

Description

After updating to the version 2.17.10, I'm having issues with this error message:

The repository of this project is this one: https://github.com/pedroapfilho/gatsby-theme-awesomeness

After the update, I can't start the example site anymore (it was made to test my gatsby theme).

The weird part is that after I publish it to NPM, it works on my website without any issue: https://github.com/pedroapfilho/website

Steps to reproduce

Download the repo:
git clone https://github.com/pedroapfilho/gatsby-theme-awesomeness.git

Run Yarn (I use yarn workspaces)
yarn

Run the example (there's a script to run the correct workspace)
yarn develop
or
yarn workspace example develop

Expected result

It should load without any warnings or errors.

Actual result

This error appears:

 ERROR #98123  WEBPACK

Generating development JavaScript bundle failed

Facing the same error. Error appears to be coming from utils/eslint-config.js line 12:

https://github.com/gatsbyjs/gatsby/blob/f488d4a82eae0c7e0aae7d47052f2fc204acf0a2/packages/gatsby/src/utils/eslint-config.js#L12

Commenting out this line causes the error to go away (though obviously other effects).

I am unsure why this is the case as changes to this file haven't occurred for some time.

Happy to provide more system details, but I encountered this in a different monorepo context.

You most likely have misaligned/different versions of packages installed.

I cloned your repo, removed the yarn.lock, run yarn install and can run yarn workspace example develop without problems. Please try upgrading all your versions (e.g. React or Gatsby) to the same version.

Thanks a lot @LekoArts, it worked. It seems that running yarn upgrade-interactive --latest and upgrading gatsby on the theme and then upgrading it on the example made this issue happen. Deleting yarn.lock and running yarn again fixed the issue.
