Xenko 3.1 Phr00t Beta Release 1
Requires Visual Studio 2019 Community (or better). Include cross-platform .NET development, Desktop .NET development (4.7.2+) and C++ development for Desktop.
Just run Xenko.GameStudio.exe to get started, once the above is satisfied.
Build projects through Visual Studio (press the "open in IDE" button), which is more reliable than using the "Play" button in Xenko.
If you don't want to use Vulkan, which isn't stable yet, modify your project's Window's csproj file & remove the <RuntimeIdentifier>win-vulkan</RuntimeIdentifier> line.
