Unhandled Exception error _VRay GPU

[M.Max]

Hello

I'm trying to render animation on Vray GPU and I'm getting these errors on random frames.
It render perfectly fine on Vray Next CPU.

[2019/Jul/9|15:46:57] error: UNHANDLED EXCEPTION: Clearing global light manager.
Last marker is at D:\cgrepo\vray\vray\src\vrayrenderer.cpp, line 4216: Preparing global light manager

And if I try to render again it ask me to restart 3ds Max
side note : why VRay log in 3ds max show only part of the log and not the full log , I would expect at least for the current render ..in this case I can't see the 5 error(s), 46 warning(s) that's mentioned in the message and I have to open the log text in notepad and search through it .
Attached the full log ..let me know of you will need the scene too
