Hi @AbrahamYezioro @Asisnath @eirannejad,
I cannot recreate this issue on my machine since I don’t have Rhino 7 license. I tested with Rhino 7 Beta, everything works fine. Would you please do one more test for me? Remove the Microsoft.Dynamic.dll in C:\Ironbug, and to see if everything would work again? Ironbug should work with the version from Rhino 7.
