I think this might originally have been caused by my forked integration, relating to duplicated class names, but (a) I've fixed that and it hasn't resolved the issue and (b) uninstalling it prior to the fix didn't resolve the issue either.

I think somehow that Home Assistant only maintains a single location/database for Python modules installed via the manifest? After an HA upgrade (ie 2024.8.0 to 2024.8.1) the problem goes away which suggest to me that the baked-in integrations and their dependencies are being re-installed over whatever's currently in place?

yes, I can confirm I did try both integrations.
