3d preview not available

Hi guys!
I have been looking to solve this problem, but couldn’t solve it. The problem is that, the background 3d preview is not appearing, even though it is checked in the view tab. Also, if I open Standalone Dynamo, the 3d preview is available there, but not in the Dynamo opened from Revit.
Thanks in advance

Hi @salmanjavaid2000 , welcome them to the community!
the same issue multiple times was solved here. please try to serch.

Thanks for the reply @_Vijay. The solution which I have seen is related to graphic drivers. I have updated versions of both (NVIDIA and Intel), but still it’s not working for me.

can you mention the Revit version and the dynamo version?

Revit 2020
Dynamo Revit
