ReferenceError: regeneratorRuntime is not vue js 2

[vadimt2]

During the debug I'm getting this issue

ReferenceError: regeneratorRuntime is not

Just after downloading the project.

I have added this code to main.js

import "core-js/stable";
import "regenerator-runtime/runtime";

and I have added "@babel/plugin-transform-runtime": "^7.13.8",
to package.json

and still I have the same issue:

ReferenceError: regeneratorRuntime is not

During debug.
