What I did:

I installed Zope and made an instance, according to the documentation. https://zope.readthedocs.io/en/latest/INSTALL.html

$ wget https://pypi.org/packages/source/Z/Zope/Zope-5.8.4.tar.gz
$ tar xfvz Zope-5.8.4.tar.gz
$ cd Zope-5.8.4
$ python -m venv .
$ bin/pip install -U pip wheel zc.buildout
$ bin/buildout
$ bin/mkwsgiinstance -d .

and

$ bin/runwsgi -v etc/zope.ini

Then, the error occurred. When I did the same process with Zope 5.8, I was able to run Zope.

OS: Debian11 Python: 3.11.2 Zope: 5.8.1, 5.8.3, 5.8.4（I didn't check 5.8.2）.

You should not use the built-in configuration, I have changed the installation docs accordingly: https://zope.readthedocs.io/en/latest/INSTALL.html#built-in-standard-buildout-configuration

Essentially, the default configuration is not pulling in Paste correctly. The minimal configuration in the section below will do that.

I got it. Thank you for changing the doc.
