Мне в итоге помогла переустановка sass-loader на более старую версию.
npm uninstall --save-dev sass-loader
npm install --save-dev sass-loader@7.1.0

Ну написано же черным по белому:

options has an unknown property 'outputStyle'. These properties are valid:
object { implementation?, sassOptions?, prependData?, sourceMap?, webpackImporter? }


нужно писать не
{
  outputStyle: 'compressed'
}

а
{
  sassOptions: {
    outputStyle: 'compressed'
  }
}
