Save Checkpoint Unable to save properly

### Custom Node Testing

- [x] I have tried disabling custom nodes and the issue persists (see [how to disable custom nodes](https://docs.comfy.org/troubleshooting/custom-node-issues#step-1%3A-test-with-all-custom-nodes-disabled) if you need help)

### Expected Behavior

Save Checkpoint Save completed

### Actual Behavior

Error saving And saving any model will result in an error

### Steps to Reproduce

### Debug Logs

```powershell
TypeError: empty() received an invalid combination of arguments - got (list, dtype=torch.dtype, device=FakeDevice), but expected one of:
