ComfyUI Revision: UNKNOWN (The currently installed ComfyUI is not a Git repository) Manager is broken?

Did a fresh comfy install. Adding manager causes a "your comfy version isn't git repo" error.

This only happens when I try to add comfyui manager. When I remove it out, the error goes away.

Also, this happens as well

When I remove manager I get this:

And there is no error. Thought at first it was something wrong with comfyui but it's the manager from what I can tell.

Start by reproducing the reported startup with ComfyUI installed without a Git repository and ComfyUI-Manager enabled. Trace the startup path that emits “ComfyUI Revision: UNKNOWN” and compare it with startup without the manager. Done means the manager handles this installation state without presenting the reported error, while the existing startup tasks still complete.
