Dynamo Sandbox preview problem in win 10

Dynamo: 2.12.0.4915

I am using latest dynamo sandbox on win 10 acer laptop with intel UHD graphics & Directx 12
Grid is displayed
Preview of geometry components is missing
Please help

Take a look on this one here…Revit 2020 Dynamo 2.1.07733 Default Background Preview greyed out

Your geometry display is working, but it looks like you are getting errors when creating geometric elements. What is the content of the yellow ‘pop up’ above the sphere creation nodes?

There is difference , in my case grid is displayed but component preview is missing .
I installed directx from here but Dynamo/DXSETUP.exe at master · DynamoDS/Dynamo · GitHub
but same problem and DirectX version is still 12

Warning: Sphere.ByCenterPointRadius operation failed.
Could not load file or assembly ‘file:///D:\dynamo-latest\LibG.ProtoInterface.dll’ or one of its dependencies. The system cannot find the file specified.

You need to install an application which the geometry library known as Autodesk Shape Manager or ASM. AutoCAD, Revit, or others will do the trick.

It means dynamo sandbox is not working as standalone application .
Can I use rhino libs

Not if you want to use the Autodesk provided geometry library.
