Hi, I get the following error when trying to enable the blender-driving-scenario-creator add-on.
Here some remarks for reproducing the error. It would be great if you could help me with this issue.

Operating System Ubuntu 18.04.6 LTS
Step where the problem occurs: Add-on (Linux and Windows)
Blender version: Blender 3.2.2
Notes: I tried installing blender both under /opt and under my home and nothing changed
Printout when trying to enable the add-on:

Read prefs: /home/aaa/.config/blender/3.2/config/userpref.blend
Traceback (most recent call last):

    from lib2to3.pytree import convert
ModuleNotFoundError: No module named 'lib2to3'

I tried to install it with ./python3.10 -m pip install 2to3 in /home/aaa/blender-3/3.2/python/bin but I didn't notice any improvements.

Thanks

This was a bug in the scenariogeneration library which should be already solved. See pyoscx/scenariogeneration#121
Could you please try installing a newer version of the library in your Blender Python environment and report back if it works again?

I started the process from scratch removing all cached python libs and the blender folder.
The latest scenariogeneration tar.gz doesn't contain your update, in fact it's older.
I'm in blender/3.2/python/bin and I run ./pip3 install --upgrade --force-reinstall scenariogeneration.
Then I opened the file blender/3.2/python/lib/python3.10/site-packages/scenariogeneration/xodr/signals_objects.py and I saw that the from lib2to3.pytree import convert was actually there.
From the file blender/3.2/python/lib/python3.10/site-packages/scenariogeneration-0.9.0.dist-info/METADATA the version is actually the latest on the repo:

If I remove manually that import, everything works fine.
I will report it to the scenariogeneration repo
