@Dr-Sassi thank you, I've submitted a few ticket , also contacted with V-Ray Support, they really interested in some cooperation about this V-Ray issue, because they've tried to replicate the freeze issue but without success. So it looks like a Maxon matter. I really hope that some reply arriving soon, because it's been a week and the freezes, and crashes continued and thats embarrassing.
I'll try to find some other ways to contact Maxon beside the Support Ticket system.
Can you help me with that?
