Revit Lookup Error after running Dynamo Python Node

Hi,

When I open Dynamo and run a Python node (— where I’m only calculating 3+5), whether it’s Python or “Python from Script”, everything works as expected. However, after this, I am unable to open Revit Lookup. Has anyone encountered a similar issue, and is there a solution?

If I debug Revit Lookup, I got this wpf error.

Looks like Revit Lookup is in conflict with one of the core DLLs which is used by Dynamo. Best to reach out to the Revit Lookup team directly via their official channels.
