ONVIF fails to load module 'cgi' since core update

Installation Home Assistant OS

Hi, my Onvif integration has stopped working since the latest (Hassio Core-2024.12.0) update.

I’m getting the following error in the logs…

The crux of the issue appears to be ModuleNotFoundError: No module named 'cgi'.

I have NO idea why, but i just restarted (5th time today), and it’s all started working. I’m extremely confused why.

I’m running into something similar, although in my case it prevents HA from starting up:

I’ve found using the HA cli to run ha core rebuild gets it back up, but restarts in general are a little more dicey now.
