Fresh install of ComfyUI Desktop fails with code 1 signal null error

### 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

I expect the program to load when I double-click on ComfyUI.exe.

### Actual Behavior

It crashes during load when I double-click on ComfyUI.exe. The background says "Unable to start ComfyUI Desktop", and when I look at the logs I see the following:

```python

```

### Steps to Reproduce

Double-click on ComfyUI.exe after installing (install, restart the program).
Wait for it to load
Reports a crash, prompts to send crash report to devs.

### Debug Logs

```powershell
I don't have a terminal that I can see, probably due to using ComfyUI Desktop. I have attached the main.log and comfyui.log files to the bug report.
