Found a solution. It seems to be an Apple Silicon problem. Compiling lxml from source, fixes the issue:

pip uninstall lxml
curl -L https://github.com/lxml/lxml/releases/download/lxml-4.9.1/lxml-4.9.1.tar.gz -o lxml-4.9.1.tar.gz
tar -xvf lxml-4.9.1.tar.gz
cd lxml-4.9.1
python3 setup.py bdist_wheel
cd dist/
pip3 install lxml-4.9.1-cp310-cp310-macosx_12_0_arm64.whl
