looks like your numpy install in ComfyUI's venv may be corrupted.

1. Go to C:\Users\valer\AppData\Roaming\StabilityMatrix\Packages\ComfyUI\venv\Lib\site-packages\ in File Explorer. Or click 3-got menu for ComfyUI in Packages tab > Open in Explorer, then go to venv\Lib\site-packages\

2. Delete any folder with numpy or ~umpy in the name.

3. Back in SM Packages tab > 3-dot menu for ComfyUI > Python Packages > + button
   Then after the "pip install" in the window that pops up, put in: numpy==1.26.4
   If the install dialog just disappears shortly after, then it was successful.

Launch ComfyUI after that.
