Karras give black image after ComfyUI update

[Creative-comfyUI]

I solved the problem using --force-upcast-attention

When I try to render an image with Karras Sampler using a batch size of 3, I get a black image with all types of Ksampler. If I use a batch size of 1 instead of 3 images, there is no black image. If I want to access the image with a batch size of 3 images without having a black image, I have to use the latent from the batch. Worst of all sometimes if I use two ksamplers in the same workflow and one is set to karras the other will also give a black image until I change the karras it is not often but it can happen. The problem seems to be the same for the simple sampler.

I have tried all possible combinations with no change. There is no error in the terminal.
