Is this a regression?

Yes, the previous version in which this bug was not present was: 7.2

Description

I did update using ng update --all --force=true (had to use --force=true because update wanted to install typescript@3.3.3333 which was not allowed (<3.3)).

After updating ng serve stopped working throwing:

ERROR in ./src/app/utils/lazy-loading.ts 71:49
Module parse failed: Unexpected token (71:49)
You may need an appropriate loader to handle this file type.
|             return __generator(this, function (_a) {
|                 switch (_a.label) {
>                     case 0: return [4 /*yield*/, import('zxcvbn').then(function (resp) {
|                             return resp.default;
|                         })];

Here is my code for lazy loading external libs:

export class LazyLoading {
  static async loadZXCVBN(): Promise<any> {
    const zxcvbn = await import ('zxcvbn').then(resp => {
      return resp.default;
    });
    return zxcvbn;
  }
}

Here is my tsconfig (nothing changed):

{
  "compileOnSave": false,
  "compilerOptions": {
    "baseUrl": "./",
    "outDir": "./dist/out-tsc",
    "sourceMap": true,
    "declaration": false,
    //    "module": "es2015",
    "module": "esnext",
    "moduleResolution": "node",
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "resolveJsonModule": true,
    "target": "es5",
    "typeRoots": [
      "node_modules/@types"
    ],
    "lib": [
      "es2018",
      "dom"
    ],
    "paths": {
      "@app/*": [
        "src/app/*"
      ],
      "@mocks/*": [
        "src/mocks/*"
      ],
      "@decorators/*": [
        "src/app/utils/decorators/*"
      ]
    }
  }
}

Can someone give me a fast solution?
