[Python] Poetry install process killed after upgrading to macOS Sequoia (15.x) with ASDF Python

I'm experiencing a persistent issue where poetry install gets killed during package installation after upgrading to macOS Sequoia. The process consistently fails at the same point during dependency installation. Environment Details

macOS Version: macOS Sequoia 15.x (upgraded from previous version)
Python Version: 3.12.9 (managed via ASDF)
Poetry Version: Latest
Python Manager: ASDF
Project: 238 packages to install from lock file

Poetry-Specific Solutions

✅ poetry cache clear --all pypi ✅ Complete Poetry reinstallation (curl -sSL https://install.python-poetry.org | python3 - --uninstall + reinstall) ✅ poetry config keyring.enabled false ✅ poetry config installer.max-workers 1 ✅ poetry env remove --all and recreating virtual environment ✅ poetry install --dry-run (works fine) ✅ poetry add requests in test project (works fine)

ASDF/Python Solutions

• ✅ asdf reshim python ✅ asdf global python 3.12.9 ✅ Reinstalled Python via ASDF (asdf uninstall python 3.12.9 + asdf install python 3.12.9) ✅ Updated ASDF and Python plugin ✅ Tried different Python versions (3.12.8, 3.11.x)

System-Level Solutions

• ✅ Updated Xcode Command Line Tools (sudo xcode-select --install) ✅ Cleared all Poetry configuration directories ✅ Tried using system Python (poetry env use /usr/bin/python3) ✅ Tried installing Poetry via pipx ✅ Attempted installing dependencies in smaller batches (--only main, --only dev)

Any insights or alternative approaches would be greatly appreciated. This is blocking development work on a large project with many dependencies.
