Why is there an error when building webpack?

Question

Frontend

When building (npm run build) with .babelrc config

{
  "presets": [
    //["env", { "modules": false }],
    "stage-3"
  ],
  "plugins": ["transform-async-to-generator"]
}

an error occurs, and if you uncomment ["env", { "modules": false }], the assembly will be assembled, BUT then
when the application is running on vue, when you click on the button, which triggers the asynchronous function, an error occurs in the console:

ReferenceError: regeneratorRuntime is not defined
    at a.sendRouter (Index.vue:221)
    at at (vue.esm.js:1863)
    at HTMLButtonElement.n (vue.esm.js:2188)
    at HTMLButtonElement.i._wrapper (vue.esm.js:7565)

Tell me how to configure babel correctly so that there are no such errors, so that asynchronous requests work and build in production does not interfere.

Leave the line uncommented and install babel/polyfill
npm install --save @babel/polyfill
