I got exactly the same error message and I reached out to CRA to make sure my info is up to date and matching what I've filled in the application and yet I still get the same error message over and over. The info on the CRA end is correct and it should match what I'm entering into the forms.
It seems there's an issue with the residency section of the form that might have a bug.
I've tried using different machines, different browsers, reset the machine, cleared browser history, different days but with no luck.
