Dynamo Background Preview for Revit 2020

Hello,

I installed Revit 2020 today and Dynamo Background preview is 2D, could you tell me what is going wrong? I had searched online and checked windows update or the basic requirement, all is fine. I read online there could be a clash with IronPython for Rhino 6 and Revit. I am not sure how to go about this, any suggestions? I installed ironpython 2.7.9
