ERROR: Exception in ASGI application

Starting fresh due to numerous issues and found a potential fix associated with updating the run.bat file.

Here is my graphics card info :

Extracted the Zip package.
Edited the run.bat so it now looks like this....

```
@echo off

call environment.bat

cd %~dp0webui

"%DIR%\python\python.exe" -m pip install --upgrade --pre torch torchvision torchaudio --index-url https://download.pytorch.org/whl/nightly/cu128

"%DIR%\python\python.exe" demo_gradio.py --server 127.0.0.1 --inbrowser

:done
pause
```

After a long install process, the application opens, but dragging/dropping an image OR clicking the "Open File" to open directly results in the following error.

h11._util.LocalProtocolError: Too little data for declared Content-Length

The report names run.bat and demo_gradio.py and includes an ASGI traceback ending in h11.LocalProtocolError. Start by reproducing the error through both image upload paths, then trace the application-side response before the uvicorn, Starlette, and h11 layers. Done would mean identifying the cause and confirming that opening or dropping an image completes without this exception.
