May be this issue is because of the low-v-ram issue.
I am not able to use it using the application, but I am able to generate images from my previous install when I ran the comfyUI using command: python main.py --lowvram --preview-method auto --use-split-cross-attention
The usual command python main.py was giving me the same black output.
We’re looking into this, but quick question - is this a very recent, fresh install of Desktop? Or have you had it / previous versions installed for a while? Just trying to narrow down the root cause.
