initiation fail: Error fetching release information

[NicoBotha]

Hi
i am on Windows and trying to install uvx --from git+https://github.com/github/spec-kit.git specify
i tried with adding my own github-token, --ai cursor-agent --script ps
all same error
│ Specify Project Setup
│ Project LeaveSystem2
│ Working Path C:\XProjects\20251212LeaveSystem │
│ Target Path C:\XProjects\20251212LeaveSystem\LeaveSystem2

Selected AI assistant: cursor-agent
Selected script type: ps
Error fetching release information
│ Server disconnected without sending a response.
│ Initialization failed: 1

│ Python → 3.13.9 │
│ Platform → win32 │
│ CWD → C:\XProjects\20251212LeaveSystem

And it crashes on this line
·Fetch latest release (contacting GitHub API)

but this code works:
uv tool install specify-cli --force --from git+https://github.com/github/spec-kit.git

I have tried so many alternatives.
Is there maybe something wrong in GitHib?

Install / setup for «initiation fail: Error fetching release information»

Package installs fail for three boring reasons more often than “the project is broken”: registry/proxy, Node/Python version, partial cache.

1. Pin versions: Node LTS or the version in the repo engines / .python-version. Don’t mix system Python and a venv.
2. If you’re on Windows + WSL or a proxy: set NODE_USE_ENV_PROXY=1 and HTTP(S)_PROXY, plus NO_PROXY=127.0.0.1,localhost for local models. Prefer the Linux filesystem, not /mnt/c, for node_modules.
3. Prefer pnpm / uv over a hung npx arborist walk. Delete lockfile-incompatible node_modules and reinstall once.
4. The log already shows Error fetching release information — search that exact string in this repo’s issues before changing random flags.

If you paste: OS, runtime version (node -v / python -V), and the first error block (not the whole npm tree), the next step is usually obvious.
