yarn start fail in dev with CRA v5.0.0

[leermao]

All the time。

I cannot run it using yarn start when set splitChunks is all

[leermao]

Is the environment used up to date and does nothing but set splitChunk

[leermao]

so I cannot set up weppack optimization in the dev environment. I found that the main setting for optimization cannot use yarn start to startup environment

@nbili it does not resolve the issue. It works for production build, but does nothing with dev mode.

Is there any issue specified regarding this in webpack repo? or any response from webpack team?

Above one would not be permanent solution I guess

I encountered the same issue, I'm using craco to configure webpack.

This doesn't solve it, just a workaround, but might help someone in the future.

webpack: {
    ...whenProd(() => {
      return {
        configure: {
          optimization: {
            splitChunks: {
