My eslintrc.cjs and stylelintrc.json files are given below along with other config files:
Package.json

stylelintrc.json

eslintrc.cjs

tsconfig.json

Specifically, look at the scripts:

    "lint:eslint": "eslint . --ext ts,tsx --report-unused-disable-directives --max-warnings 0",
    "lint:eslint:fix": "eslint . --ext ts,tsx --report-unused-disable-directives --max-warnings 0 --fix",
    "lint:stylelint": "stylelint '**/*.{css,scss}'",
    "lint:stylelint:fix": "stylelint '**/*.{css,scss}' --fix",

npm run lint:stylelint

> [email protected] lint:stylelint    
> stylelint '**/*.{css,scss}'


  141:3  ✖  Unexpected empty line before declaration  declaration-empty-line-before

✖ 1 problem (1 error, 0 warnings)
  1 error potentially fixable with the "--fix" option.

PS C:Usersmubtairclient> npm run lint:stylelint -- --fix

> stylelint '**/*.{css,scss}'


scss/globalStyles.scss

The fix flags do not actually fix the problem. At some point, it did use to, but I do not know what change caused it to stop working. So I added the “:fix” extended script and that works.

npm run lint:stylelint:fix  

> [email protected] lint:stylelint:fix
> stylelint '**/*.{css,scss}' --fix

Curiously, npx with –fix flaf works as well:
npx stylelint ‘**/*.{css,scss}’ –fix

The same behaviour can also be seen with eslint as well.

I have tried reinstalling node, npm and have also tried ncu. As a last resort, I tried deleting node modules along with package.lock.json. That did not work either. It should be noted that I am aware that there is a newer major version of eslint available, but I could not make my project work with flat config so decided go for the newest legacy config. Anyways I do not think that is major issue as stylelint with —fix is not working properly either.
