The above workaround didn't have any effect, so I'm using the previous version of antfu/eslint-config:

npm i -D @antfu/eslint-config@2.21.0

You should also fix your package.json to the version you choose, so that future attempts to run npm install don't reach for the latest version: that is, remove the caret in

"devDependencies": {
    "@antfu/eslint-config": "^2.21.0"
}

Try to override dependency, than install @antfu/eslint-config@latest (npm i @antfu/eslint-config@latest) and run npx again

[nyxb]

The point of the thing is to be able to execute npx @antfu/eslint-config@latest in a new project to install everything with the cli and unfortunately this is no longer possible.
