Custom Node Testing

• I have tried disabling custom nodes and the issue persists (see how to disable custom nodes if you need help)

Your question

Hi, i have a manual comfyUI installation on windows. Yesterday i updated ComfyUi with the ComfyUI-Manager. Since then I get the following error with dirrefent nodes (for example CheckpoitLoaderSimple with the default image generation workflow from the templates:

I tried several ComfyUI versions and i tried to manually update comfyUI again and install the requirements, but the error remains.

Do i have to delete ComfyUi and do a complete reinstall?

I am also experiencing this issue with the latest update. I submitted a bug report and included all details. Workflow is the built in wan 2.2 5b itv. I tried both the portable version and the installed version, same error. Cuda 12.9

[IxalonDarkstone]

I went back to Cuda 12.8. It solves a lot of Comfy issues.

[Mystos007]

Do you have the Comfyui Lora Manager?

Updating that fixed the error for me.

[AkiraSan67]

Do you have the Comfyui Lora Manager?

It works! Thanks!
