I tried to building the app with fresh install and it worked without any problem. Try to remove node_modules folder and yarn.lock file and reinstall dependencies. Then, try to run build script again.

yarn run v1.22.5
$ cross-env NODE_ENV=production webpack --config webpack.build.config.js --mode production
