at require (node:internal/modules/cjs/helpers:94:18)The thing is CLIEngine was deprecated in ESLint v7 and removed in v8 (which is right now in beta).
Also rules from ESLint cannot be required:

}Because they are not exported anymore. According to migration guide, rules should be used this way:
-import baseRule from 'eslint/lib/rules/brace-style';
+import {builtinRules} from 'eslint/use-at-your-own-risk';
+const baseRule = builtinRules['brace-style'];
