TypeError: Class extends value undefined is not a constructor or null

The reason for the error is that when the version of mini-css-extract-plugin is greater than 1.3.5, when speed-measure-webpack-plugin is used, the title error will be reported
webpack version: 5.27.2
webpack-cli version: 4.5.0
speed-measure-webpack-plugin version: 1.3.1
mini-css-extract-plugin version: >1.3.5

Modify the version of mini-css-extract-plugin to 1.3.5 to solve the problem
