Console logs

The console log does not confirm any particular circumstances.
It is usually the same as the image is created.

Additional information

In version 1.7.0rc, a path domain error was displayed when the bf16 model was operated. https://github.com/AUTOMATIC1111/stable-diffusion-webui/issues/14167

The 1.7.0 official version does not display that error, but it can be generated, but it is being generated as a black image.

For me, it's 100% reproduced.
