1-use 2020.2-R3
2-disable opengl/material previews
And load scene

Also got this error on a different scene:
OctaneRender Studio 2020.2 (10021201)

OptiX error for device 0: [ERROR] failed to pack SBT header
OptiX API error for device 0: Invalid value
OptiX error for device 0: [ERROR] "sbt->raygenRecord" is null
OptiX API error for device 0: Invalid value

Any ideas what this means?

It opened with R3!!
Here's to hoping it's stable for me

What you mean sorry? OK or not?

Yes, sorry... it works now since I upgraded to R3.
I hope it keeps working.
So far so good
