Rhino 7 - Open Grasshopper file and it crashed

Hi, I just downloaded Rhino 7 Evaluation today and it seems not to work with my grasshopper file from Rhino 6. The grasshopper screen turn red and I don’t know what to do.





Hi - I’ve put this one in the Wallacei category for the time being as that is being referenced in the error messages.

Is this happening with this one Grasshopper file only or can you reproduce the issue with a new file in Grasshopper on Rhino 6 and only using a few components?
Can you post a file that causes this behavior?
-wim

Also, if you are using rhino 7, make sure you have Wallacei for Rhino 7 installed on your machine… you can download the rhino 7 version here: https://www.food4rhino.com/app/wallacei-0
