RxJS 6: Cannot find module 'rxjs/operators'

Still looks like there is an issue with this. Creating a new TS project and adding the RxJS dependency. Now adding the imports used in the above projects, eg:

import { animationFrameScheduler, Observable, range, zip } from 'rxjs';
import { map } from 'rxjs/operators';

And you get the error: Cannot find module 'rxjs/operators'

For an example see https://stackblitz.com/edit/typescript-dquxft?file=index.ts

If I clone one of the working projects above and use that as a starting point then it is working - same content/code and dependencies in both project. See https://stackblitz.com/edit/ts-rxjs6-test-ommwas?file=index.ts

@LayZeeDK it looks like the issue is actually coming from Number.MAX_SAFE_INTEGER in fizzbuzz.ts which is creating a loop that is too big for the browser to handle responsively. If you change the end of the range to something smaller the example seems to work fine:
