I have a 2080TI. You are correct about this being a recent update issue.
I also noticed a lot more crashes after the last 2 updates.
Which graphics card are you using?
I tracked down a possible driver issue on nVidia 2060RTX.
The internal error is "Cuda error at cuCtxCreate: Illegal Address"
This also happens in Blender after rendering for a long time and especially when video is playing in another window.
A workaround for devs is to recreate the iRay context when this exception is thrown, once this exception is thrown the Cuda context is invalid and cannot resume.
You are going to edit a submitted issue. This issue will be changed to private draft mode until you click submit again. Are you sure?
