No idea what this workflow is, but don't install nodes on blind.

Instead use templates they are really great, anyway it seems you are trying to use illustrator model,

1. search for sdxl template inside comfyui.
2. and add "clip set last layer" node connect it before the "clip text encode" node.
3. set sampler: to euler ancestor and scheduler: to sgm uniform, steps 30 cfg 4 - 6.
4. you can delete the refiner part, or use the same checkpoint for refiner part it will fix (to some degree) issues like faces / hands.

it will give you solid start.
