Steps to reproduce:

Open the attached project
Open the New Scene
Enter Play mode
Observe that animation-duration can be set to float.Epsilon without the Editor crashing or throwing errors in Play mode
Build and run the project

Actual results: The player crashes on "UnityEngine.UIElements.UIAnimationBinder::SampleClip_Injected()"

Expected results: The player keeps running as in Editor Play Mode
