Thank you both! I will try a fresh install of Revit this weekend.
Just FYI, a reinstall did NOT fix the issue.
Thanks for the update, here’s a link if you just want to see/use the samples for now. You can unzip (using 7zip) into the folder here and it should work:
C:\ProgramData\Autodesk\RVT 2025\Dynamo\Samples\

This helps a lot, thanks, John!
