Did you ever find a fix?

[brandonros]

I fixed it with this in webpack.config.js:

const webpack = require('@nativescript/webpack')

module.exports = (env) => {
  webpack.init(env)
  webpack.mergeWebpack(env => {
    return {
      optimization: {
        concatenateModules: false
      }
     }
  })
  return webpack.resolveConfig()
}
