Hi @carl-westman_8110 ,
The error message means that the database wasn't updated as per normal during the start-up process. It's hard to guess why, as we have special handling for that.
It's likely that restarting the service would have fixed it, but downgrading and then upgrading would also force an upgrade as well. Unfortunately it's hard to say at this point.
Upgrading to 2025.10 should be fine.
Thanks,
Alana
