Input System Error Spam

I get a constant stream of errors in the log when I hit play, without fail, every time even after project reload.

```CS
InvalidOperationException: You are trying to read Input using the UnityEngine.Input class, but you have switched active Input handling to Input System package in Player Settings.
UnityEngine.UIElements.DefaultEventSystem+Input.GetAxisRaw (System.String axis) (at :0)

```

I directly downloaded the v1.10 sample project and made no modifications. I'd suggest changing the `Active Input Handling` setting in Player Settings to `Both` as evidently something is still using it.
