### What happened

I attempted to import a model from my previous existing models in ComfyUI, whenever the hash step completes, the python back-end crashes and after 10-20 seconds gives an exit code in the launcher console.

Here is the link to the model that I used:
https://huggingface.co/nolual/majic/blob/main/dreamshaperXL10_alpha2Xl10.safetensors

From what this is telling me, torch is throwing some manner of error upon exiting the hashing step, however it should go without saying that this model has no problems importing and running in ComfyUI, and has never thrown me any manner of issues. This leads me to conclude some point following the conclusion of this step, it isn't properly handled by InvokeAI. Naturally, I am not remotely acquainted with this code base, so I couldn't really say for certain this isn't user error, i.e, installation on a separate drive somehow causing some manner of issue.

I also did a control experiment, using a different model:
```
[ModelInstallService]::INFO --> Model install started: H:/[Redacted]/[Comfy_Install]/ComfyUI/mo
dels/checkpoints/anything-v4.5-inpainting.safetensors
Hashing anything-v4.5-inpainting.safetensors: 100%|████████████████████████████████████████████| 1/1 [00:12<00:00, 12.94s/file]
[ModelInstallService]::INFO --> Model install complete: H:/[Redacted]/[Comfy_Install]/ComfyUI/m
odels/checkpoints/anything-v4.5-inpainting.safetensors
```

It properly imports this model, so it isn't ALL imports that aren't working.

### What you expected to happen

...I expected the model to import.

### How to reproduce the problem

It does state in the log that this is an import, but I'll lay out a bit more deeply where in the menu I went. I opened the launcher, the launcher opened the interface, from the interface, I selected
Models -> Scan Folder
Then I put the location in, pressed 'Scan Folder', then manually selected the model I was trying to import, dreamshaperXL10. It then began the hashing step, upon waiting 10-20 seconds, it finishes the hashing step. At that point, 5-10 seconds later I got a 'python crashed' windows prompt, then 10-20 seconds later I get the exit code in the console.

### Additional context

I attempted to search for pre-existing forms of this issue, but the only thing I saw related to downloading models, and specifically flux related issues. This model is an XL fine-tune, it's not something I could find any pre-existing bug reports or solutions for.
