Revit Freeze when scatter applied with Vray7

I updated to Vray 7 on my Revit 2024.3 and now my scatter grass applied to a toposolid will render once but will freeze Revit and I will have to close the program.
I tried to the same setting with the same file in Revit 2025.3 and with my template with the same result.
The grass scatter was working just fine with Vray6, but I can go back my vray setting being saved in the Vray7 format.

Thanks for your help in advance.
