I can no longer AirPlay to my Apple TV 4K... its works from my wife's phone, as she has not upgraded to 18.4 yet.

Anyone else? It just spins and eventually times out.
 
I was having issues with multilingual keyboard after the update, and a restart fixed the issue. You should try to restart your phone to see if it fixes it for you.
 
AirPlay uses a few protocols that can single out a device and leave others working. Restart the AppleTV, iPhone and the router. Are you using a VPN? If so try disabling it temporarily to remove variables.

I admin a few hundred iDevices and Macs for a school - on some devices iOS/iPadOS 18.4 had access right problems (leading to airplay or casting problems) which disappeared after shutting the devices down and powering them up again (a simple restart did not help).
