Seems like you are running a newer version of Pydantic than was pinned in the Home Assistant project, or, looks like you have cython 3 in your Python environment, which has a known issue with Pydantic at this point (see: pydantic/pydantic#7689)

That's strange. I found the issue report for pydantic, too, but so far I don't see where that would be coming into my setup. As mentioned in the description, I have the pydantic version that HA prefers:

(py3.11) homeassistant@idefix:/srv/homeassistant$ pip show pydantic
Name: pydantic
Version: 1.10.12
Summary: Data validation and settings management using python type hints
Home-page: https://github.com/pydantic/pydantic
Author: Samuel Colvin
Author-email: s@muelcolvin.com
License: MIT
Location: /srv/homeassistant/py3.11/lib/python3.11/site-packages
Requires: typing-extensions
Required-by: zwave-js-server-python

(The "py3.11" portion of the prompt is the virtualenv name.)

...and at least as far as I can tell I don't have Cython installed. Neither pip nor aptitude know anything about that:

(py3.11) homeassistant@idefix:/srv/homeassistant$ pip show Cython
WARNING: Package(s) not found: Cython

pi@idefix:~ $ aptitude show cython3
Package: cython3

As Workaround, after testing several versions of pydantic, my HA running well with pydantic 1.10.10

$ pip install pydantic==1.10.10
$ python -c "import pydantic.utils; print(pydantic.utils.version_info())"
pydantic version: 1.10.10
pydantic compiled: False
install path: /srv/homeassistant/lib/python3.11/site-packages/pydantic
python version: 3.11.2 (main, Mar 13 2023, 12:18:29) [GCC 12.2.0]
platform: Linux-6.1.55-v7+-armv7l-with-glibc2.36
optional deps. installed: ['typing-extensions']

Good find! pydantic 1.10.10 works for me, too. So I suspect HA may need to be pinned to that version instead? 🤔 (At least until pydantic is fixed, that is.)

Sorry for the newbie question but are you able to direct me on how / where I would go about rolling back to pydantic 1.10.10 so I could use this fix for the short term? (I see the code above but have no idea where this would go) , using raspberry pi3, home assistant core-2023.10.1

Found a solution to have pydantic-1.10.12 working as HA requirement.
Installing package from GIT source !!!

Stop HA

$ sudo -u homeassistant -s -H
$ source /YOURVENVPATH/bin/activate
$ cd $HOME
$ mkdir install-pydantic
$ cd install-pydantic
$ wget https://github.com/pydantic/pydantic/archive/refs/tags/v1.10.12.zip
$ unzip v1.10.12.zip
$ pip install ./pydantic-1.10.12
$ python -c "import pydantic.utils; print(pydantic.utils.version_info())"
pydantic version: 1.10.12
pydantic compiled: False
install path: /srv/homeassistant/lib/python3.11/site-packages/pydantic
python version: 3.11.2 (main, Mar 13 2023, 12:18:29) [GCC 12.2.0]
platform: Linux-6.1.55-v7+-armv7l-with-glibc2.36
optional deps. installed: ['typing-extensions']
$ cd $HOME
$ rm -rf install-pydantic

Start HA
