iRay render unstable, crashes at random points.

Sometimes iclone crashes whenever I run an iray render. The only solution is to save the project as a new file and save the frames in a different folder.

OS: Windows 10

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.
