Cannot read property 'jsonData' of undefined (webpack5 and storybook/html)

Describe the bug I started a project using npx sb init --builder webpack5 and chose html for my future components. I cannot edit the stories because the builder breaks.

To Reproduce I start the project with npm run storybook and whenever I try to edit and save anything (like a .stories.js) the hot module restarts building but breaks immediately with an error:

webpack building...
3% setup watch run/Users/raduchiriac/Projects/-node/sb-temp/node_modules/@storybook/builder-webpack5/node_modules/webpack/lib/json/JsonGenerator.js:119
		let data = module.buildInfo.jsonData;
		                            ^

TypeError: Cannot read property 'jsonData' of undefined

Seems to be fixed in webpack v5.42.1:

Could be fixed by setting:

package.json

...
"resolutions": {
    "webpack": "5.42.1"
  }

It seems very much unrelated to storybook now. Focus moved here: https://github.com/webpack/webpack/issues/13691
