TextMeshPro NullReferenceException on MaterialReferenceManager.cs

Unity 2021.1.28f1 for Nintendo Switch.

I have some random errors with TextMeshPro.

Code (CSharp):

1. NullReferenceException: Object reference not set to an instance of an object
2. TMPro.MaterialReference..ctor (System.Int32 index, TMPro.TMP_FontAsset fontAsset, TMPro.TMP_SpriteAsset spriteAsset, UnityEngine.Material material, System.Single padding) (at Library/PackageCache/com.unity.textmeshpro@3.0.6/Scripts/Runtime/MaterialReferenceManager.cs:525)

5. TMPro.TextMeshProUGUI.OnPreRenderCanvas () (at Library/PackageCache/com.unity.textmeshpro@3.0.6/Scripts/Runtime/TMPro_UGUI_Private.cs:1644)

Can you see if you get the same behavior using the latest preview release which is version 3.2.0-pre.3 for Unity 2020.3 or newer?
