Same, it works fine with next dev but fails on next export

I had the same problem, to export I import the css file into _app.js with
import "antd/dist/antd.css"

my next.config.js has a less wrapper in the css one.
return withCSS( withLess({ lessLoaderOptions: { javascriptEnabled: true}}))

and the babelrc is this:
{ "presets": ["next/babel"], "plugins": [ [ "import", { "libraryName": "antd", "style": false }, ], ["@babel/plugin-proposal-decorators", { "legacy": true }], ["@babel/plugin-proposal-class-properties", { "loose": true }] ] }

but this solution loads the whole css file which is around 600kb, so this is not a practical workaround
