Added a figure to my scene and now renders are black

I had a scene that I just rendered and decided to add another figure and now when I hit render it instantly gives me a black frame. I tried reloading the same scene to before I added and that file also renders black. Does anyone know how to fix this issue?
I just updated my gpu driver after I was able to start rendering with cpu checked in advanced settings. After updating my driver I unchecked cpu again and it still renders black. So im guessing there is a issue with my gpu?

Have you tried to restart Daz Studio?
Have you fallback to CPU enabled?
If CPU fallback is unchecked, it might be that the additional character causes that you are running out of VRAM, so no available render.
What does your log say?
where do i find the log? Also this problem is happening with previous saves of the same scene without the figure added
Log is in Help > Troubleshooting > View Log File
i checked the log file and there is this string at the end

i have restarted my computer multiple times so I dont understand why I have no GPU memory available
Well, the first line says it is out of memory, so I would assume that the memory allocations higher up in the log has filled the available memory.
Memory use is highly dependant on subD level of the characters, as well as if you are dForce (SBH) hair.
let me attach the whole file and see if you can see anything. I am new to daz and im unfamiliar with all the jargon. I was able to reload the scene from a previous save and it would render. When I added the third figure however it clearly didnt like it since it rendered black again
The log is quite a mess... First of all, you are apparently using Iray Viewport while trying to render in Iray - This may already cause the rendering to stop due to lack of VRAM (as fallback to CPU has been disabled)
Does not affect rendering, but keeping/saving stuff on Onedrive is really a bad idea.
Your log is missing all the information from starting DS (important information)
It looks like to me that you are using an ultrascenery environment. That takes up some ressources too.
And then there is a bunch of images. And after that it loads a character with SubD set to 4, but that is changed to SubD 2 to reduce geometry.
So for sure you are running out of memory.
Due to ultrascenary, you can try to go to render settings > Optimization > Instancing Optimazation. That should be on memory. If not you can try to change it and see if it improves anything.
Open Task Manager and watch the GPU status. Dedicated GPU memory usage will give you an idea of what's happening. If it maxes out, the render will likely fail without CPU fallback. You can change one of the graphs to show CUDA use, which is an indication of whether the GPU is being used to render.
I think the third figure is the one that is subd4 and being reduced. At this point I'm just going to render it with the cpu since I was planning on letting it cook for 12 hrs anywys
Are you over-/underclocking your GPU or system in general?
If you are using Texture Shaded Viewport, do you have the secondary Viewport visible and is it also texture shaded?
Something in your scene is causing the rendering to start over and over and over again and I thought it was the Viewport - The repeated render attempts, combined with a possible memory leak, may also be the cause for running out of VRAM
If you are using the denoiser, disable it.
Take your rendering settings down to basic (default), that could give an idea of what is the culprit.
+1 I only use it for screen shots. Othe wise it back evrything. (eg: desktop, pictures, and My Documents), My documents which by default is where your scenes are stored. Then files on demand takes over and stuff just get lost. Here are my setting for Onedrive below.
Hope this helps more than one person.
It has the same controls as the primary Viewport has, but if it's not in use, close it to save screen space.
Right-click on the tab that says 'viewport' and there is an option to close it.
