Ladybug won't calculate

When I use Ladybug_Forward Raytracing Compornent in Rhino6 ,My computer freezes at the moment the calculate starts.

If I use Rhino5 , that phenomenon doesn’t occur.

There are some available compornent in Ladybug tool, but most occur freezes.

What do you think I should do?

Which version of Ladybug are you using? Please attach the Grasshopper definition that you are having problems with.
Also, there’s a dedicated forum for LB | HB here:
