Description

### Expected Behavior

hidream-e1 works

### Actual Behavior

I updated comfy to latest version, and download the bf16 hidream-e1 checkpoint. When the load diffusion model nodes runs, it just crashes the comfy without any error message.
I have two rtx 5090 cards and 96GB RAM. And the hidream-l1 fp8 workflow works well for me.
If someone has it working with 3090, why will not 5090?
I try fp8 or default option in load diffusion node, nothing is different.
It seems to crash between clip and diffusion loading.

### Steps to Reproduce

run a hidream-e1 workflow
