[Bug]: Loading SDXL model crashes unexpectedly.

Nobody has claimed this yet.

### Checklist

- [ ] The issue exists after disabling all extensions
- [ ] The issue exists on a clean installation of webui
- [ ] The issue is caused by an extension, but I believe it is caused by a bug in the webui
- [X] The issue exists in the current version of the webui
- [X] The issue has not been reported before recently
- [ ] The issue has been reported before but has not been fixed yet

### What happened?

I am using the --always-cpu flag to run exclusively on the CPU, however, upon attempting to load the SDXL model, it crashes instantly (owing to inadequate available RAM—having only 12GB in total, the system has to rely on virtual memory swapping, which is the fundamental reason for the crash). In the original web UI, the SDXL model loads properly and generates images without any problems.

### Steps to reproduce the problem

None

### What should have happened?

None

### What browsers do you use to access the UI ?

### Sysinfo

None

### Console logs

```Shell
Loading weights [8421598e93] from E:\StableDiffusionForge\models\Stable-diffusion\AnythingXL_xl.safetensors

```

### Additional information

_No response_

Start by reproducing SDXL model loading with --always-cpu and the AnythingXL_xl.safetensors model referenced in the report. Inspect the loading path reached before the console stops and compare behavior with the original web UI. Done means the model loads without crashing on the reported CPU and memory setup, or the failure is narrowed to a documented limitation.
