Some of unit tests fail

I am following these steps to run the unit tests (using Windows 11):

Clone the repo
- git clone git@github.com:PoliUniLu/cora.git
Navigate to project folder
- cd cora
Create a new a conda environment
- conda create --name cora_env python=3.9
Activate the environment
- conda activate cora_env
Install poetry, pytest, and the package
- pip install poetry
- pip install pytest
- poetry install
- Run unittests
- poetry run pytest

I get two failed tests:
