Bug TypeLoadException: Could not load type of field 'TMPro.TMP_FontAsset:m_FaceInfo'

When running the EditMode TestRunner test GetPlayerSettingsTest in Unity 2021, I get this error stopping the tests running. This does not happen on Unity 2019. I am using TextMeshPro 3.0.6

Code (CSharp):

1. TypeLoadException: Could not load type of field 'TMPro.TMP_FontAsset:m_FaceInfo' (5) due to: Could not load file or assembly 'UnityEngine.TextCoreModule, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies.

Still getting this! Maybe it's just me
