Error: PostCSS received undefined instead of CSS string

I am using typescript + vue 3 to develop a google chrome extension, when I build my app, shows error like this:

Error: Module build failed (from ./node_modules/vue-loader/dist/stylePostLoader.js):
Error: PostCSS received undefined instead of CSS string

this is the package.json:

and this is the webpack config:

const CopyPlugin = require("copy-webpack-plugin");

      },
      
      {

        use: [MiniCssExtractPlugin.loader, "css-loader"],
      },
      {
        test : /\.(scss)$/ ,
        use: [MiniCssExtractPlugin.loader, 'css-loader', 'sass-loader']
      }
    ]
  },
  plugins : [
    new VueLoaderPlugin(),
    new CopyPlugin({
      patterns: [
        { from: "src/manifest.json", to: "manifest.json" },
        { from: "src/resource/image", to: "resource/image" },
      ],
    }),
    new MiniCssExtractPlugin({
      filename: "[name].css",
      chunkFilename: "[id].css",
    }),
    new HtmlWebpackPlugin({
      filename: 'popup/popup.html',
      template: 'src/popup/index.html'
    }),
    new webpack.DefinePlugin({
      __VUE_OPTIONS_API__: false,
      __VUE_PROD_DEVTOOLS__: false,
    }),
  ]
};

what should I do to fix this problem? I am searching from internet that someone told that the node-sass is not imcompatible, but I am not using node-sass right now. where is the problem?
