Uninstalled old ComfyUI from drive C and reinstalled onto drive D (for space). Worked OK once, but had to do another reinstall and now it stops as I’m trying to open/create an Instance. I have now completed multiple reinstals and reboots and updated the NVIDIA drivers. Nothing.

I’m not a programmer – so this is almost meaningless to me. I’m comfortable using things like Blender, After Effects, and Premiere, and when it works ComfyUI is excellent – but something like this is an issue almost all the time. Very frustrating. This should be a tool, not a bad experience.

Any help appreciated.

Win11 pro, 128G Ram, 5090 Nvidia.

I encountered the same problem. I reinstalled requirements and it started working, but I’m unsure if it will have any impact in other environments.

“.\.venv\Scripts\python.exe” -m ensurepip --upgrade
“.\.venv\Scripts\python.exe” -m pip install --upgrade pip setuptools wheel
“.\.venv\Scripts\python.exe” -m pip install --no-cache-dir --force-reinstall --prefer-binary -r requirements.txt

Thanks!

When i get a chance I’ll try it.
