As you know, recently ComfyUI cannot be updated through the Manager and the process fails with an “Update Failed” error.

I have prepared a quick tutorial showing exactly how to fix this without reinstalling a fresh portable version. 

If you are experiencing failed updates, missing nodes, or workflows refusing to load (including Z-Image), make sure to watch this video. I will guide you step-by-step through a safe fix that updates your current ComfyUI.
