Strange error after OS 5.12 upgrade

After upgrading to OS 5.12 yesterday, I started getting this configuration error upon boot:

Component error: 7homeassistant - Integration ‘7homeassistant’ not found.

Everything seems to work OK but I have no idea what is causing the message.

I am running latest CORE, OS, and Supervisor on a Pi4.

Any ideas?

Can you find “7homeassistant” anywhere in your configuration.yaml?

I went back to my backup image MicroSD, reinstalled the OS and I don’t get the error anymore. Most likely user error of some sort. My config has grown into a 5000 tentacle monster after running HA for years. I have so much to clean up and streamline. Thank you so much for the reply!
