Next >14.0.1 cannot use @ant-design/icons (unexpected token 'export')

[BaileyMillerSSI]

Link to the code that reproduces this issue

https://github.com/BaileyMillerSSI/next-ant-design-demo

To Reproduce

1. Create a new project with npx create-next-app@latest (I selected typescript, tailwind, src dir (pages), and other defaults)
2. npm install @ant-design/icons
3. Modify the index.tsx file to include an ant design icon

Current vs. Expected behavior

Displayed error:

~\bad-ant-icons-demo\node_modules\@ant-design\icons-svg\es\asn\AccountBookFilled.js:3
export default AccountBookFilled;
^^^^^^

SyntaxError: Unexpected token 'export'

In an existing project I was previously on Next 14.0.1 and upgraded to 14.1.1 to resolve the published security issue. After upgrading I was unable to use ant-design/icons. This is demo is in a fresh application.

Expected:
@ant-design/icons would be usable within the base project. I have tried changing the package.json to be type: module and that has no affect. It seems that either or both of these are true; something was broken in next during the upgrade to >14.0.1 or ant-design/icons had a bug hidden in it that upgrading next to >14.0.1 exposed as a build error.

Additional context

As far I can tell this appears to be an issue with @ant-design/icons BUT next didn't complain about it until >14.0.1. With teams upgrading to resolve the security issue fixed in next 14.1.1 I suspect that more users will run into this issue.
