Describe the Bug

ESLint doesn’t work after updating eslint-config-next to version 12.1.1. I assume it’s because you locked the dependencies https://github.com/vercel/next.js/pull/34823, but I also use the eslint-plugin-import.

Oops! Something went wrong! :(

ESLint: 8.12.0

ESLint couldn't determine the plugin "import" uniquely.

- /path-to-project/node_modules/eslint-plugin-import/lib/index.js (loaded in ".eslintrc.json » plugin:import/recommended")
- /path-to-project/node_modules/eslint-config-next/node_modules/eslint-plugin-import/lib/index.js (loaded in ".eslintrc.json » eslint-config-next/core-web-vitals » /path/node_modules/eslint-config-next/index.js")

Please remove the "plugins" setting from either config or remove either plugin installation.

If you still can't figure out the problem, please stop by https://eslint.org/chat/help to chat with the team.

Before I realized it’s from the eslint-config-next package, I removed the rules in my config files that used the import plugin then the error was

Oops! Something went wrong! :(

ESLint: 8.12.0

ESLint couldn't determine the plugin "react" uniquely.
