Create-React-App not working in Edge Browser

I am currently playing around with React, starting with Create-React-App Boilerplate, which I downloaded following https://reactjs.org/docs/create-a-new-react-app.html.

In Chrome the code works pretty well, however, in Microsoft Edge the brwoser windows remains blank white without any output.

I have not modified the Create-React-Package in any way, however, this also holds true for apps that I wrote according to tutorials: Working great in Chrome, but Edge simply shows a white screen as if no code was executed at all.

Do I need some additional package to make React Apps run in the Edge Browser?

Your help is much appreciated. Thanks in advance,
