Chromecast with Google TV not showing up in Google home

[piperthedj]

I have multiple Chromecast that were casting fine. Now, none of them show up in Google home.
I already did the basics,

• Make sure the Chromecast device is within 15 to 20 feet of the setup device and the WiFi router.
• Restart the router: Disconnect the Wi-Fi router from the socket and leave it unplugged for 2 minutes.
• Make sure to connect your Chromecast device and phone to the same Wi-Fi band (2.4 or 5 GHz).
• Restart the Chromecast device: Remove the Chromecast device from the power source. Leave the device unplugged for one minute, then plug it back in.

All devices are running on the 5GHz band, with DHCP, strong wifi signal, and running with DHCP.
I can ping all devices but they will not show up in Google Home.

any help is appreciated.

time is synchronized for both devices
Both devices are on the same wireless network
Both devices are running on the 5GHz band
Both devices have been restarted multiple times
Chromecast was reset and everything worked fine for a day.
Location sharing is enabled
Android device is running Android 11. This is not the cause because another setup just like it is working fine.
I can't get the firmwear version because the Chromecast will not show up in Google home
There are no pending updates
Android TV OS: STTL. 2405-08.005

I am past the basic stuff. I need someone whose knows what is going on please.

More information. Hope you don't mind.. I'm trying to get you as much information so we don't have to go back and forth with things I've already done.
In my set up, I have one unit that has functioned properly from day one. It is the only one out of many Chromecast that has functioned as advertised without any question. I think I know why.

I started comparing units line by line.

The functioning unit, the Android OS TV Build is STTL.240508.005.12011027 with a kernel version of 4.9.269

All of the units that function intermittently have an Android OS TV Build of STTL.240508.005 and a Kernel version of 5.4.259-android-12-9-g95db6f1dfeac

these are the only differences I can see between a functional unit and a non functional unit.

What do I need to do to get these to match?
