❔ Non-nullable property must contain a non-null value when exiting constructor

I know what it says and what it wants my to do. However, my situation is: I have a bunch of objects (as properties) and that not all of them needs instantiating in a main class constructor. Given a condition, some will be and some won't be. In case of one that won't be, I still have no idea how to make the warning go away. Any suggestion? I'm sure how to Google this since using the warning would send me to a non-desirable direction.

❔ Cannot start OmniSharp due to error on MacOS

The error said I haven't install .NET 6 SDK for arm64 even though I tried to install it TWICE. I can still run code and stuff, however the Intellisense or the Code Outline doesn't seem to work because they need OmniSharp. How do I fix this?

OmniSharp server started with .NET 6.0.402
.
    Path: /.vscode/extensions/ms-dotnettools.csharp-1.25.7-darwin-arm64/.omnisharp/1.39.6-net6.0/OmniSharp.dll
    PID: 83500

[STDERR] Unhandled exception. 
[ERROR] A .NET 6 SDK for arm64 was not found. Please install the latest arm64 SDK from https://dotnet.microsoft.com/en-us/download/dotnet/6.0.

❔ Using `with` to create a new record in return statement result in an error

    private Point GetNewPosition(Commands command, Point position)
    {
        if (command == Commands.MoveNorth) return position with { Y++ };
        if (command == Commands.MoveSouth) return position with { Y-- }; 
        if (command == Commands.MoveEast) return position with { X++ };
        if (command == Commands.MoveWest) return position with { X-- };
        return null;
    }
  public record Point(int X, int Y);

    private Point GetNewPosition(Commands command, Point position)
    {
        if (command == Commands.MoveNorth) return position with { Y++ };
        if (command == Commands.MoveSouth) return position with { Y-- }; 
        if (command == Commands.MoveEast) return position with { X++ };
        if (command == Commands.MoveWest) return position with { X-- };
        return null;
    }
  public record Point(int X, int Y);

I'm trying to make new records using with statement, but it resulted in an error saying The name 'Y' does not exist in the current context Can anybody help explain? Thanks
