I recently posted on the Github with a bug that the latest Next version is unable to build when an @ant-design/icon exists on the page. After doing some testing I found that this started happening in 14.0.4. This seems like it should be a bigger deal and I cannot seem to find a lot of other people reporting similar issues. I have found 1 other person with a similar bug.
After v14.0.4 I get unexpected token export when trying to render an ant design icon with the pages router.
