On windows poetry cannot self update. If you run poetry install and on of the packages installed is a different version of poetry windows will throw an error that looks like the following (mainly the permission error part of this)

[2023/09/05 18:28:40.090]   PermissionError: [WinError 5] Access is denied: 'Z:\\data\\mci\\ae68c42c2af0b203b416c9ffe7d4824a\\venv\\Lib\\site-packages\\~ulwich\\_diff_tree.cp39-win_amd64.pyd'

The correct way to handle this is to install poetry into a separate venv then bootstrap that venv to install the normal venv.
