This problem has been bothering me for a long time and cannot be solved. Spline_Editor_InstanceDiffusion_kijai_01.workflollow also reported this error.

Hi, thanks for reporting.

Could you go into your ComfyUI/models/instance_diffusion directory and delete the checkpoint files in there? It's possible that they downloaded incorrectly and a corrupted file is in there.

If that doesn't work and you're trying to use the nodes in the meantime you can download them from the ComfyUI manager models section by searching for Instance Diffusion.
