HTML-5 Ads dont work with Google Display Network (Animate 2020)

Hello 

We create ads for the google display network and since the new Animate update to 2020, they have stopped working. They are simply displayed in white without an error message.

We are not allowed to use external urls on the google display network and therefore use the js libary hosted by google.

So we edit the html-file from:

<script src="https://code.createjs.com/createjs-2015.11.26.min.js"></script>

to: 

<script src="https://s0.2mdn.net/ads/studio/cached_libs/createjs_2015.11.26_54e1c3722102182bb133912ad4442e19_min.js"></script>

With Animate 2019 the Ads works fine. See attached Files. Any solutions?
