ComfyUI suddenly fails to find Python package under Windows

Hello, I installed comfy UI yesterday successfully using the Windows installer, I tried several workflows and all runs good.

Today when I start it up, I get a “maintenance” screen, mentionning python package not found. I clicked on “install” , then the launcher stucked there for hours. Don’t know what to do.

The Console Logs don’t change, and I can not input any command in this console
