I’m getting the below error while attaching the script to game Object
“The script dont inherit the native class that can manage a script”

using Unity.Entities;
using Unity.Mathematics;
using UnityEngine;

public struct PlayerInputData : IComponentData
{
    public KeyCode upKey;
    public KeyCode downKey;
    public KeyCode rightKey;
    public KeyCode leftKey;
}

You forgot to generate authoring component of the script!

using Unity.Entities;
    using Unity.Mathematics;
    using UnityEngine;
    [GenerateAuthoringComponent]
    public struct PlayerInputData : IComponentData
    {
        public KeyCode upKey;
        public KeyCode downKey;
        public KeyCode rightKey;
        public KeyCode leftKey;
    }
