I've been using comfyui just fine all day. I close out and come back to it an hour later and cant get back in raise AssertionError

### Expected Behavior

When I click "run_nvidia_gpu" file on a windows computer (Comfyui Windows portable) I expect terminal to launch Comfyui for me in Firefox

### Actual Behavior

Terminal gives me this error and says "press any key to continue" and then terminal closes and comfyui doesnt open. Full terminal code pasted under debug log below.

### Steps to Reproduce

Double click "run_nvidia_gpu" file within Comfyui Windows Portable. then go to manager and install Lora-Training-In-Comfy. I'm not the only person to have this issue: https://github.com/comfyanonymous/ComfyUI/discussions/3802
