I could reproduce this behaviour and I am pretty sure this is caused by missing .NET Core 1.1 runtime libraries. When you go to C:\Program Files\dotnet\shared\Microsoft.NETCore.App you probably won't see the '1.1.0' directory.
Go to https://www.microsoft.com/net/download/core and install the SDK library (select Current and SDK).
N.B. If you did try (as I suggested in one of my comments) to remove the "type": "platform" line (and adding the runtimes part (depending on your windows version) then you'll see it won't crash. Without having to install the runtime / SDK.
