NullReferenceExceptionin the Burst compiler when multi-dimensional arrays were used. The compiler now produces a correct error message telling users that multi-dimensional arrays are not supported by Burst.

UI Toolkit: Fixed disabled state not showing properly after hierarchical changes were applied. (1321042)
Universal Windows Platform: Fixed word suggestion not appearing in the Windows On Screen Keyboard when editing an InputField or TextMeshPro control. (1332468)
