Amazon GameLift Anywhere (Compute type "Managed EC2" works / Compute type "Anywhere" does not work)

I was able to successfully start my game via Gamelift using the compute type "Managed EC2" and the corresponding build upload from my game (Windows 2012 R2).

Now I have tried it with Compute type "Anywhere" and followed this step by step guide: https://latam-es-resources.awscloud.com/aws-news-blog/introducing-amazon-gamelift-anywhere-run-your-game-servers-on-your-own-infrastructure

When I start my game server here on my hardware (laptop), the startup hangs when executing "Init SDK" and does not continue.

Btw: If I run GameLiftLocal on the laptop and then start the game server, the game server starts without problems.

I do not understand what is missing here. Do I need to install anything else on the target hardware (laptop) for "Anywhere Fleet" or create any prerequisites? I use a Windows 10 Pro laptop for "Anywhere Fleet".
