Rhino 6 crashing on start up

I’ve been dealing with this issue on and off for a while now, and this is the 4 time it’s happened.
I’ve had a constant issue with Rhino crashing on start up, which will happen for no apparent reason, and then go away for no other apparent reason. The previous times this has happened, I’ve done everything I’ve been told by tech support, including:
-Starting it in safe mode and disabling all plug-ins that don’t ship with Rhino. (Doesn’t start)
-Updating graphics card drivers
-Updating Windows
-Contacting Tech support, who haven’t really been able to help, as much as they’ve tried.
-Reinstalling Windows 10, which is a right pain.

Things I’ve done previously to attempt to fix this issue:
-Start up in safe mode and do the plugins thing
-Update Graphics card drivers
-Update Windows 10

Here is the Rhino Debug Message:
RhinoDebugMessages.txt (19.0 KB)

Getting this fixed is quite pressing, so I can’t just wait for it to clear up (Which in and of itself is problematic), and having this issue come back again is definitely not something I want to deal with.
Hopefully something in here can clear this up. Let me know if there’s anything else I should include.

Thank you for any time and help.

Hi -

Can you provide a bit more background to this? It sounds like this is not occurring regularly. Is this 4 times in a week or more like 4 times in 4 years?

I just check with the eMail address that you use on this forum but can’t find any crash reports. Are you getting the crash reporter dialog when you experience a crash?

Please run the Rhino SystemInfo command and copy-paste the result here.

It’s been happening, as far as I can recollect, since around march. over the summer I’ve experienced this issue around 4 times, this current one being the fourth.

I don’t. The crash occurs without any input on my end beyond starting the program. It always occurs around the same point during the start-up process, right after the pop-up window displays “preparing viewports” as the current process. Below is an image of the moment it crashes.
