Importing CSS modules works only if the as syntax is used.

Bug report

Beginning with version 7.0.0, importing CSS modules works only if the as syntax is used.
Using "allowSyntheticDefaultImports": true, "esModuleInterop": true intsconfig.json doesn't help

Actual Behavior

if importing without * as like this import styles from "./counter.module.css"; it throws the error "TypeError: Cannot read properties of undefined (reading 'button')"

Expected Behavior

importing import styles from "./counter.module.css"; shouldn't throws errors

How Do We Reproduce?

Import CSS modules without * as syntax

I'm also experiencing this. Also see #1599 which was closed for not using an issue template.

Please read migration guide - https://github.com/webpack-contrib/css-loader/releases/tag/v7.0.0, set namedExport: false (https://github.com/webpack-contrib/css-loader?tab=readme-ov-file#namedexport) if you want to use old syntax, it is a breaking changes and I strongly recommend to migrate on * as syntax
