Thank you. This solves the error. Errors started happening when I upgraded electron

fixed

you can add these text with .electron-vue/webpack.web.config.js and .electron-vue/webpack.renderer.config.js file,in HtmlWebpackPlugin.

      templateParameters(compilation, assets, options) {
        return {
          compilation: compilation,
          webpack: compilation.getStats().toJson(),
          webpackConfig: compilation.options,
          htmlWebpackPlugin: {
            files: assets,
            options: options
          },
          process,
        };
      },

It helps for me. Thanks a lot
