@youtux You were right! It was pytest-bdd-html after all! I will raise in their repo.
Thanks a lot for your effort.

As mentioned in #679 (comment), pytest-bdd works fine with pytest-xdist and it's tested against it.
I even tried reproducing the issue installing py3.7, pytest==7.4.3, pytest-bdd==6.1.1, pytest-xdist==3.5.0, but I don't see any error.
If it doesn't work for you, please first try to upgrade your dependencies (as you seem to be using outdated versions of pytest-bdd, pytest and pytest-xdist).
If it still doesn't work, please provide a MCVE so that I can debug the issue.
Closing this unless more info is provided.

Thanks for your reply. @youtux
Posted the issue on pytest-xdist git, and the devs there said the issue lies with pytest-bdd:
pytest-dev/pytest-xdist#1038
I can reproduce the issue on my demo project, https://github.com/AmirYa412/Pytest-BDD-Project
Note: Need to replace in requirements.txt file from pytest-parallel to pytest-xdist==3.5.0.
Simply installed dependencies on a venv, and ran pytest -n 2 command reproduced the issue for me on MacOS Sonoma.
Dependencies:
pytest==7.4.3
pytest-bdd==6.1.1
pytest-bdd-html==0.1.14a0
pytest-html==3.2.0
pytest-metadata==3.0.0
pytest-xdist==3.5.0
requests==2.31.0
urllib3==1.26.12
Sadly in my company, we are running on Python 3.7 for now, so upgrading to latest pytest-bdd version is currently impossible. I will try running my project with 3.11 and update in new comment.
Here is the full error log:

Try removing the pytest-bdd-html dependency, that's the one causing the error.
