I’ve used this forum post (Rhino64 bit crashes on startup) to narrow down that my issue is souly reliant on Vray and nothing else. I have a few number of plug-ins and have did what was stated in the post with everything not causing issues but rhino. The weird part is that Vray was literally working an hour or two ago and from one second to another it just stopped working on the file and would crash it. Other files work fine with Vray but it just seems that on this file only it decides to cripple it. Any advice welcome.
