Is my first gen unusable? "Could not communicate with your Chromecast" error

I moved and got new WiFi so I did a factory reset on my Chromecast. Google Home says download the Device Utility.

Here's what happens with Device Utility:

  1. You must turn off WiFi to connect. Done.
  2. Connect to your Chromecast temporary WiFi: Find the WiFi being displayed on the TV.
  3. Connect to said WiFi, go back to Device Utility app.
  4. "Connecting to Chromecast"... Error: "Could not communicate with your Chromecast".

Not really sure what to do with it at this point other than throw it in the garbage. Anyone ever resolved a similar issue?

Edit: Ok so anyone who sees this who was a Pixelbook/Chromebook: luckily I own one. I used the Home app on it and it works like normal instead of making you download this Device Utility trash. Owning a Pixelbook can't be the only solution here... Is it?!
