    The issue still exists and in 2021.3.44f

    I am still getting this error in 2022.3.10 after having queued a certain amount of events in a non-main thread.

    It is pretty easily reproducible by, for example in a script like this:

    using System.Threading;
    using System.Threading.Tasks;
    using UnityEngine;
    using UnityEngine.InputSystem;

    public class Test : MonoBehaviour
    {
    Gamepad gamepad;
    CancellationTokenSource onDestroyCancellation = new();

    void Start()
    {
    gamepad = InputSystem.AddDevice<Gamepad>();

    Task.Run(async () =>
    {
    var ct = onDestroyCancellation.Token;
    while (!ct.IsCancellationRequested)
    {
    await Task.Delay(10);//Wait 10 milliseconds

    for (int i = 0; i < 50; i++)//Queue up 50 delta state events (can also just be state events)
    {
    InputSystem.QueueDeltaStateEvent(gamepad.leftStick, new Vector2(1, 1));
    }
    }
    });
    }

    void OnDestroy()
    {
    onDestroyCancellation.Cancel();
    }
    }

    I admit that 50 events per 10 milliseconds is quite a lot. If I decrease the amount to 10 events per 10 milliseconds (1 event per millisecond - still quite a lot) I sometimes get the error, sometimes not. But it is not very reassuring that this error CAN occur - I don't dare to queue up the events in another thread.
