AEM Sites not working with latest SDK

[cornsen]

I downloaded and started a local Cloud AEM instance from

https://experience.adobe.com/#/@adu-training/downloads/content/software-distribution/en/aemcloud.html

e.g. Version: AEM SDK v2020.02.2291.20200219T233521Z-200130
as it is described on:
https://github.com/adobe/aem-enablement/tree/master/AEMAsACloudService/07_Cloud_Ready_Quickstart

When the instance is up running, i can reach all functionalities except the /sites.html part.
Reason:
Internal Server Error
Cannot serve request to /sites.html/content in /libs/granite/ui/components/coral/foundation/columnview/columnview.jsp

I tried multiple SDK's and got the issue on all of them.
Oracle JDK 11 is installed
