On Unpause (5/5 runs) - StraightLineCast has 0 length array

See original GitHub issue

Environment

Unity 2020.3.16f1

Code source: Zinnia
Code version: 1.40
Platform version: Android 10 ( API 29) , Pico VR ( old/new Unity SDK)
3rd party dependencies: None

Steps to reproduce

Create simple rig with CameraRigs.TrackedAlias and 2 interactable pointers
Add Straight Pointers for left/right hand. Make it always visible. Set activations so that the activation event is always processed (pointer is always active)
Build Android Project and run on Pico
Launch App
Press Home button to navigate to Pico Quick System Menu. Wait for few seconds.
Go back to your app ( continue your app)
Sometimes it will throw out of boundary exceptions. ( 5/5) tries

This is also reproducible on Quest 1.

Expected behavior

It should have a check for length before using indecies.

Current behavior

ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index ?, line 0, in System.ThrowHelper.ThrowArgumentOutOfRangeException ?, line 0, in System.ThrowHelper.ThrowArgumentOutOfRangeException ?, line 0, in System.Collections.Generic.List`1[T].set_Item ?, line 0, in Zinnia.Cast.StraightLineCast.GeneratePoints ?, line 0, in Zinnia.Cast.StraightLineCast.DoCastPoints ?, line 0, in Zinnia.Process.Moment.MomentProcess.ProcessNow ?, line 0, in Zinnia.Process.Moment.MomentProcessor.Process ?, line 0, in UnityEngine.Camera+CameraCallback.Invoke
