I have the same problem. However, it worked with Docker 20.10.23-143.
With 24.0.2-144 it stopped working. The error message is identical to yours.

Other containers seem to work fine (also with port configs). So I am not sure if it is Docker or AdGuardHome.

I have found a solution here: https://stackoverflow.com/questions/38517272/docker-proxy-error-starting-userland-proxy-while-trying-to-bind-on-443

Edit /etc/docker/daemon.json and add

{
    "userland-proxy": false
}

Don't forget to restart the docker service:
sudo systemctl restart docker.service

I don't know what the implications are of disabling the docker userland proxy.
It seems to simply use other methods of port forwarding, such as iptables. In that case it should be fine to do so.
