I cant build in Server Development mode

I am following this tutorial: How To Make A Multiplayer Game With Unreal Engine and Amazon GameLift (Part 2 - GameLift Server SDK) - YouTube
When I want to build the code in Server Development mode it says me this error: “Server targets are not currently supported from this engine distribution.”

I use UE 4.25 (but I tried with 4.24.3), Visual Studio 2019.
