Crash upon starting R7 or R6

I was goofing around with some PBR material assignments in R7 to learn more about how to get Cycles rendering to compare with old Octane and Thea renderings and having great results. I was getting a lot of crashes at first but I think was making progress until just now when I had a file hang and I had to force quit Rhino. I wasn’t bothering to submit the crash reports until I did a restart. I restarted R7 and still got the crashes right after opening. Didn’t matter if I double clicked the desktop icon to start or went to the pull down and ‘opened’. I can open in safe mode but when it has to load plugins it looks like Thea render will trigger a crash. I have just updated my Nvidea drivers and everything I can image with no joy! Any ideas?

Here is what I get when I run SysInfo

It looks like when I open R7 in Safe Mode I only have wireframe and Thea mode available. I’m thinking that Thea is the culprit here but haven’t used it for weeks.

I’ve sent a dozen crash reports in on this and hope to see some response from that.

Having the same problem. Crashing every time I try to hit render. Hard to get hold of Thea support team
