I was able to fix it by changing my two-factor authentication from authenticator app to text authentication. I also ended up changing my password too in the process so if it doesn’t work for you by just switching the two-factor method I would try a combination of changing/disabling two-factor authentication and changing your password.
I hope that fixes it for your too!
I am assuming once it’s linked back to Google Home, You should be able to switch the settings back to whatever you want.
