Revit for Workspace Layout

Hello,

I am trying to run the Workplace Layout study (link below). I reworked the file to run in Revit 2020. It works fine using a simple room, with doors and windows. However, when using a room with curtain wall, it crashes immediately after hitting ‘Run’ in Dynamo.

A room with curtain wall works in Revit 2021. So I am guessing it has to do with Revit / Dynamo versions.

Using Revit 2020.2.4 with Dynamo 2.3.1

I was wondering if anyone might be able to offer some suggestions to get around this if I want to keep working in Revit 2020?
