After installing manager, Comfy/Manager is unable to find PIP or UV in the embedded Python

[cgwers]

I hadn't noticed until today that it's been the manager causing this issue. Prior to installing manager, Comfy runs nicely. After installing, something happens that makes PIP and UV unavailable and Comfy begins dying piecemeal until it won't launch. It might take a few days, but it'll quite launching soon after this message starts appearing.

Why won't manager use the embedded PIPI and UV?

Having the same problem on Linux. Did you pull from git head?

Fundamentally, Python has a complex dependency ecosystem, so it is not feasible to install and operate all Python applications within a single Python environment. For this reason, each Python application is run inside an isolated Python environment—such as a venv or the python_embeded environment included in ComfyUI Portable. This is also why installations are performed using the command:

path/to/the/running/python.exe -m pip

Try running the following command in the Windows command prompt and check whether it works correctly:

\\10.0.33.217\share3\ComfyUI_windows_portable\python_embeded\python.exe -m pip
