Hi,
I'm trying to run Plone 6 with ZEO but the instances are not starting and I get the following error:

Traceback (most recent call last):

The instance is configured with buildout and venv.

Can anyone help me?

Thanks

Hi! which python version and how did you install Plone?

I'm using python 3.9.

I'm using buildout to configure and install Plone.
