Problem with rendering
Hi,since yesterday evening I have a problem with daz,after about 2 seconds after clicking the render button the application pauses rendering with a blank window.From the logs it looks like not enough vram but earlier I rendered images on this scene and nothing like this happened One g

What happens if you try to render with 3Delight, does that work or also generate some errors? You may want to start by trying to rule out possible issues. If 3Delight works as intended, then what happens if you switch your viewport to Filament and then also Iray?
3Dlight works normally, if I switch to iray view, it looks stuck, image doesn't "clear"
Your log is saying that you have run out of VRam and that CPU is not enabled. If you think the scene should not be using that much might save and restart the computer to see if that frees it up.
Also if you are trying to render with iray preview on that takes up vram also.
On a windows system I like to use "Task Manager" to monitor my GPU usage. Right click on lower task bar, select Task Manager. Select the "Performance" tab in Task Manager. On the left there shoud be a GPU listed ... pick your GPU and it will tell you lots about the resource usage for the GPU.
