Backup integration failing to start on 2026.1.2 | Home Assistant | Page 1

I think the issue is that I accidently ran 2025.1.2 when trying to start the 2026.1.2 container. I was coming from 2025.12.5.

I'm getting the following error:

Source: setup.py:425
First occurred: 8:55:55 AM (1 occurrence)
Last logged: 8:55:55 AM

Error during setup of component backup: 'state'
