[NeuralFault]

Are you using ESET security software?

[Postbenji]

Yes, I am. Is it blocking something?

[Postbenji]

Thanks for putting me on the right path @NeuralFault. I added an exception to ESET's HIPS for Data\Packages\ComfyUI\venv\Scripts\python.exe and that let me update the ComfyUI package. I initially tried adding the HIPS exception for the Assets folder as per this thread, but that didn't work. Maybe it's because I was upgrading, rather than running a fresh install of ComfyUI.
