So I think I know what the issue is, llvmlite==0.36.0 only supports Python 3.6-3.9, but the script has Python 3.12.12. I have no idea how to fix it, because I don't know the location of the python environment to get into it and try either uv pip install "llvmlite>=0.40.0" or uv pip install --upgrade open-webui to see if it can update separately.
