Open3D just added support for Python 3.12 with 0.19.0, but you are using Python 3.13.
Also, your error message states, that it wants to install open3d==0.18.0, but latest version is 0.19.0.

I would recommend using a virtual environment like venv with a pyproject.toml or requirements.txt defining your dependencies.
Personally, I am using uv for that, which can also help with changing your Python version:

uv init --python 3.12 # Initilize your project with python version 3.12 (also creates some starter files)
uv venv # Create a virtual environment
uv add open3d # Install open3d to your venv
. .venv/scripts/activate # Enable your venv
python myapp.py # Run your script
