Vray doesn't render my latest file, but with other files it does

Hi guys, I have SketchUp 2017 and V-Ray 3.4 and I encountered a strange problem.

When I want to render my files I dont have any problem except with my last project (file).

When I click to render it doesnt work, It begins for 2 secs and it interrupts without to show even the frame buffer…I dont understand why, could you help me please? :frowning:

How big is the file?

I have the same problem.
Did you find the solution at last?
