Data shapes crashing Revit in 2025

I have a script that I have been using to batch create sheets successfully up to and including Revit 2024. It uses Data-Shapes nodes for a UI interface to select the sheets to be created.

I have seen from similar posts that Revit 2025 needs to run IronPython 2.7 version 3.2.1 so have installed that package (however I get the message that I need to install IronPython 3.2.0 - which I have also tried and I have the same issue). The Data-Shapes version is 2025.3.118.

When running the script in 2025 Revit crashes and I have no error message. I have identified that this happens at the UI.Listview Data node.

I would be very grateful if anyone can let me know what I am doing wrong?
