Python crashes in creative_interpolation_example.json workflow

Hi,
Inspired by your workflow show cases on Reddit, I imported your "creative interpolation example" workflow into my ComfyUI setup. All seems well until the workflow reaches the RGB SparseCtrl node. Immediately Python crashes. I'm having a Mac Studio M2 with MacOS Sequoia (v15.3.1) and I'm using Python v3.13. What could be the problem? Of course if needed I can give you more details! TIA!
