InputSystem stopped working and registers no input of any kind now

macOS 10.14.6 Mojave
Unity: 2020.1.17f1
InputSystem: 1.0.1

Very basic InputSystem WASD + Mouse

It had been working for the last week as I developed my CharacterController, then today it stopped working without error or notice.

It’s a very basic setup

Very simple implementation:

private PlayerControls pcon;
...
private void Awake()
{
    pcon = new PlayerControls();
}
...
private void Update()
{
    var lookInput = pcon.Gameplay.Camera.ReadValue<Vector2>();
    Debug.Log(lookInput); // This always returns 0,0,0 now
}

Other keys never trigger a started/performed event etc. I’ve tried deleting the generated class and recreating it, there is no change.

Input Debug shows the Mouse and Keyboard are present and supported. Focus isn’t an issue, and I’ve stepped through about a dozen somewhat adjacently related issues across the forums. It was configured and working as recently as an hour ago then just died.

I really have no idea what is going on. Restarting hasn’t helped.

I accidentally stumbled across my cause. During my refactors/rewrites I somehow left this little handy bit behind. I hope this may help someone who stumbles across this in their searches. Don’t forget to enable your controls like this idiot

    private void OnEnable()
    {
        playerControlsVariable.Enable();
    }
