Not working on AMD card after trying a few things listed on here.

### Checklist

- [X] The issue exists after disabling all extensions
- [X] 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
- [X] The issue has been reported before but has not been fixed yet

### What happened?

Trying to run forge with my 6750 XT, to no avail, tried:

-COMMANDLINE_ARGS= --directml --skip-torch-cuda-test --always-normal-vram --skip-version-check
-comment out all the @torch.inference_mode() (add # before them) on: \ldm_patched\modules\utils.py - line 407 \modules_forge\forge_loader.py - line 236, line 242
change "with torch.inference_mode():" for "with torch.no_grad():" on: \modules\processing.py - line 817

CPU and GPU seed gen, restarted my pc, nothing.
only using a single SDXL checkpoint.

the only thing I get as a result is:
typeerror: 'nonetype' object is not iterable

### Steps to reproduce the problem

AMD gpu..

### What should have happened?

should work from what I have seen on here

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

Mozilla Firefox

### Additional information

_No response_

Start with modules_forge/forge_loader.py around line 250 and trace its call from modules/sd_models.py lines 509 and 585 while launching with the reported DirectML arguments. Reproduce the SDXL checkpoint-loading failure and verify that the model loads successfully without the reported NameError.
