HomePod help, I can not get past the iCloud sync part

Purchased 2 HomePods on 3/14/24 along with newest 4k Apple TV.

Everything worked fine. Was able to stereo pair them to Apple TV.

Around latest update one of the HomePods stopped working. I really didn’t notice until I played a video and noticed stereo was gone.

The HomePod (left) that stopped working will no longer connect to WiFi. The other HomePod (right) worked fine until I reset it. Now the right will do everything except pair with iCloud. I get error 7005 over and over. I updated both my iPhone 15 pro max and iPad mini to latest iOS. Activating HomePod with iPhone or iPad gets error code 7005

I reset Fios router. I have reset both HomePods multiple times I unplugged and held top touch pad left still can not find WiFi right still gets 7005 error.

I have activated both as tv speakers and non tv speakers. Right now very frustrated. Couple hundred dollar bookends.

my last resort is taking them to my office and see if I can pair these with work Wi-Fi the router there is eero brand.
