Error on Debian 12 installation

Tried to install on fresh Debian 12 VM (here: all updates installed - but this doesn't matter):

error: externally-managed-environment

× This environment is externally managed
╰─> To install Python packages system-wide, try apt install
    python3-xyz, where xyz is the package you are trying to
    install.

    If you wish to install a non-Debian-packaged Python package,
    create a virtual environment using python3 -m venv path/to/venv.
    Then use path/to/venv/bin/python and path/to/venv/bin/pip. Make
    sure you have python3-full installed.

    If you wish to install a non-Debian packaged Python application,
    it may be easiest to use pipx install xyz, which will manage a
    virtual environment for you. Make sure you have pipx installed.

    See /usr/share/doc/python3.11/README.venv for more information.

note: If you believe this is a mistake, please contact your Python installation or OS distribution provider. You can override this, at the risk of breaking your Python installation or OS, by passing --break-system-packages.
hint: See PEP 668 for the detailed specification.

For your information NIXStats is not maintained any more, I spent some time trying to debug issues and get help during the previous year but wasn't able to receive any answer.

The founder of NIXStats sold their business to webpros, the owners of Plesk, last year. You can see they have integrated it into their product under the name https://360monitoring.com

This is a problem with Ubuntu 24 as well... Ubuntu 24 comes with Python 3.12 and it is not compatible with nixstats' install script.

Update: I've corresponded with 360monitoring support. They say they support Python 3.12 since May. Their price levels seem similar.
