I suspect the issue may be linked to this other issue with html-webpack-plugin

A temporary solution, temporarily ignore the detection of HtmlWebpackPlugin

const SpeedMeasurePlugin = require("speed-measure-webpack-plugin");

const smp = new SpeedMeasurePlugin();

const config = smp.wrap({
  mode: 'production',
  entry: [paths.appIndexJs],
  output:{ // omitting},
  plugins:[
    // new HtmlWebpackPlugin({ // omitting}), // remove
    MyPlugin(), // omitting
  ]
})

config.plugins.unshift(
  new HtmlWebpackPlugin({ // omitting }),
)

module.exports = config

module.exports = config

but when I config link this, there is no result about how much time of the plugin speed
