Issue: [Bug]: I am unable to use img2img with new GPU
Labels: bug-report

### Is there an existing issue for this?

- [X] I have searched the existing issues and checked the recent builds/commits

### What happened?

I switchet PCs to one which is more capable. Img2img however stopped working. I tried enabling upconversion to float32 in options. That did not help.

### Steps to reproduce the problem

1. Go to img2img
2. add image (any size)
3. add prompt
4. click generate

### What should have happened?

generation based on image should begin

    modules.devices.NansException: A tensor with all NaNs was produced in Unet. This could be either because there's not enough precision to represent the picture, or because your video card does not support half type. Try setting the "Upcast cross attention layer to float32" option in Settings > Stable Diffusion or using the --no-half commandline argument to fix this. Use --disable-nan-check commandline argument to disable this check.
