I can't upgrade the setuptools package past version 69.5.1.post0

Describe the issue

When I set setuptools in my pyproject.toml file to setuptools = "^75.2.0" and try to build my project with the nix build command, I get the following error.

> - setuptools<76.0.0,>=75.2.0 not satisfied by version 69.5.1.post0

No matter what I've tried, my setuptools is always pinned to that version.

I ran the nix flake update and poetry update commands to make sure there where no conflicting dependencies. Every other package in my project updated properly, but setuptools was held back.

Here is my pyproject.toml:

[tool.poetry.dependencies]
python = "^3.11"
<other packages>
poetry-core = "^1.9.1"
setuptools = "^75.2.0"

[build-system]
requires = ["poetry-core>=1.9.1"]
build-backend = "poetry.core.masonry.api"

Here is the packaged in my poetry.lock

[[package]]
name = "setuptools"
version = "75.2.0"
description = "Easily download, build, install, upgrade, and uninstall Python packages"
optional = false
python-versions = ">=3.8"
files = [
    {file = "setuptools-75.2.0-py3-none-any.whl", hash = "sha256:a7fcb66f68b4d9e8e66b42f9876150a3371558f98fa32222ffaa5bced76406f8"},
    {file = "setuptools-75.2.0.tar.gz", hash = "sha256:753bb6ebf1f465a1912e19ed1d41f403a79173a9acf66a42e7e6aec45c3c16ec"},
]

How can I stop setuptools from being pinned to 69.5.1.post0?

Dup of #1729

I mean, that conversation didn't come to a conclusion about the problem. Do you know how to solve it?

Solution, I had to move from nixpkgs-24.05 to nixpkgs-unstable.
