Reproduce the Windows startup failure and inspect prestartup_script.py, ComfyUI/nodes.py, and the GitPython files shown in the traceback, especially git/__init__.py, git/remote.py, and git/cmd.py. Determine whether the failure belongs to ComfyUI-Manager or the antrobots-comfyUI-nodepack import path. Done means startup completes without the reported IndexError and ImportError.
