hi @shenlant314 , would you be able to please confirm

• have you restored all NuGet packages for the solution ? could also try to reinstall them.
• do you have any Autodesk products installed, such as Revit or AutoCAD ? If so, what versions ?

As you might be aware, Dynamo Sandbox is distributed without the ASM geometry libraries, so an Autodesk product needs to be installed for those to be found. Sounds like that's either not found or a different version than expected.

I have restored all NuGet packages for the solution，and Revit 2020 has installed。
