[BUG] Python process exited with code 1 and signal null during setup. None of the maintenence steps work either. All information enclosed.

### 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

ComfyUI to install without Errors.

### Actual Behavior

# Error During Install

During the initial install, after I've selected my processing device (GPU) and settings location (I left it at the default directory), I get an error:

```log
An error occurred: Error
Python process exited with code 1 and signal null

I've attached all of my logs from `C:\Users\username\AppData\Roaming\ComfyUI\logs` here.

### Other

The binary I used to install **ComfyUI** is named `ComfyUI Setup 0.7.2 - x64.exe` that I downloaded here from GitHub.

## Maintenance Window Options

I've tried running all options in the "Maintenance" window:

- I have `uv` installed already, so this step is not necessary. (Even though I already have `uv` installed, I did try it earlier and it made no difference)
- I have the latest VC++ Redist installed, so this step is not necessary.
- I've tried the `Reinstall ComfyUI` button, and I get the same errors.
- I've tried the "Install Python Packages" button and I get the following console output after clicking `Console Logs`:

```powershell

- I've tried the "Reset virtual environment" (Recreate) button and I get the following console output after clicking `Console Logs`:

```powershell

```

- I've tried selecting a different "Base path" (The first button on the Maintenance screen). I set it to "C:\AI Data\ComfyUI". After doing this, there is no output in the "Console Logs" (The window that pops up when you click on the "Console Logs" button), but at the top of the window there is text that says `Status: Error" and it's colored in red. Screenshot:

Finally, I can't get the application to start. When I click the continue button, I get a message saying `Unable to continue - errors remain`.

So I am completely at a loss.

# Computer and OS Information

Here is my Windows 11 Version information from `winver`:

Really hope someone can help me because ComfyUI looks awesome.

Thanks so much.
