I've seen some posts from customers who created a second home to bypass the "assisting device" error. They were then able to remove the camera from the second home and add it to their original home. Apparently this works because the camera retains the Wi-Fi settings when it is removed from the second home (the same Wi-Fi credentials it was trying--and failing--to get from the "assisting device:), and is then able to use those Wi-Fi credentials to join your original home.
What happens with your second camera? Maybe if removing the first camera from the second home and adding it to your original home works, you can then try adding the second camera to the now-empty second home and repeat the process. If it all works, you can then delete the now-empty second home.
By the way, customers have been reporting "assisting device" issues in this forum for over a year. Many seem to occur when there's a thermostat involved. One customer recently theorized that the thermostat is too complicated a device to be used as an "assisting device", causing the process to fail. Some customers resort to removing their thermostat from the Google Nest app or Google Home app temporarily (depending on the thermostat). We don't have a Nest thermostat and have not encountered the "assisting device" error in adding 3 new cameras/doorbells in the last year.
