Google Nest Community

For me it was the name of my device

This was the link:https://myaccount.google.com/connections 

I was able to fix it by searching for it under my account and deleting the link. In my case I searched “Sony” and removed all links. It removed it instantly and my now Google Home is looking normal again

I to am having this issue. Sony TV that I cannot 'unlink' no matter what I try. I've even created a new home and moved everything but it follows me
