Answer 1

I was able to fix this issue by deleting node_modules and yarn.lock. After that I ran yarn to rebuild node_modules and then yarn start worked without an issue.

From the webpack-dev-server v4 migration guide:

fs , index , mimeTypes , publicPath , serverSideRender , stats , and writeToDisk (related to webpack-dev-middleware ) were moved to devMiddleware option.
