Well, I just shot myself in the fooot. Updated to 4.11 without setting s restore point and now can not render. Gettting errors all ove the place in the log file Just giving every one a heads up to hold up for a few days on their update.
Here is what I got when clicking the render button It can not find my 1070 even though it is checked.. Going to dry updating my driver first but baring that something is definately wring with 4.11

My sister is having the same problem. She tried rebooting the computer, no luck. Uninstalling DAZ and reinstalling, still no luck. Now she's in the process of restoring to an earlier point in time, but it's taking forever. They should have made sure things like this don't happen before it's released.
I had the same issue with a newer version of 4.11, however when I updated my nVidia drivers, rendering worked just fine.
Yes that was it. Updated to the latest Nvidia driver and can now render
How does one update the Nvidia driver? Mine works fine and I can render, but I think others may have this issue.
The drivers are probably available in their website. I haven't updated mine.
https://www.nvidia.com/download/index.aspx
I encounter the very same issue. Upgraded to 4.11, and even after updating all Nvidia drivers I still get these errors:

2019-06-15 18:52:26.700 Iray Render error: Invalid parameters (NULL pointer).
I upgraded to the last drivers (430.86) on my GeForce GTX 1060, and it now refuses to render. I even chose the game ready or the studio configuration, nothing changed.
What, if anything, is checked in the Advanced tab of Render Settings?
Photoreal Device: GeForce Checked
Interactive Device: GeForce Checked
OptixPrime Accelaration: checked
In both cases, CPU is left unchecked. That setting worked perfectly fine in 4.10, but still refuses to operate in 4.11. It instantly finishes the render.
Have you tried disabling OptixPrime?
I tried disabling OptixPrime, nothing changed.
Here are the logs:

Please post a screen shot of the Advanced tab of Render Settings.
Here is my configuration. With this, tne render instantly finishes with only a blank canvas. If I want to render, I have to check "CPU". Weirdest part is that after doing a few CPU render, if I uncheck CPU, it will sometimes detect my GPU and the render will go fine.
Once again, this issue appeared after upgrading to 4.11.
I always have to start with one or a few CPU renders. Yesterday, I was unable to get the GPU to work, while some other time it's fine.

Updating NVidia drivers did not work for me. Anybody know where I can download a copy of 4.10 Pro still?
Be careful with killing the task, the reason it's still running might be it's running cleanup on temporary files and things like that.
4.10 is not available for download anymore now that 4.11 General Release is out. You can try contacting Daz support to see if they can provide you with a copy,
