[Bug]: flow typecheck fails due to malformed_package_json

Describe the bug

Flow responds with an error when I upgrade storybook to the latest version.

To Reproduce

Run npx storybook@latest upgrade on a project that had storybook@7.6.3 to update the storybook to 7.6.4. This was also a problem when I ran that script to update storybook from 7.5.3 to 7.6.3.

Run npx flow.

Error message:

Found  1 error

System

ubuntu2004 and on a macbook pro with sonoma 14.1.2

Additional context

I looked up the file in the node_modules directory, and it just has a single open curly bracket.

Reverting @storybook/react-webpack5 to 7.5.3 resolves the flow error, but that package isn't kept in sync with the other storybook packages.

Running storybook locally works as expected with react-webpack5@7.6.4
