[FATAL] listen udp 127.0.0.1:53: bind: address already in use

sudo netstat -tulpn | grep :53

I'm having the same problem.
I installed dnscrypt without any issues, but when I restarted my computer to check if everything was working correctly, I got the same error:

Netid State Recv-Q Send-Q Local Address:Port Peer Address:Port Process
udp UNCONN 0 0 127.0.0.1:domain 0.0.0.0:* users:(("dnscrypt-proxy",pid=811,fd=7))

mptcp LISTEN 0 4096 127.0.0.1:domain 0.0.0.0:* users:(("dnscrypt-proxy",pid=811,fd=8))

Following the installation guide, it clearly appears that a previous instance of dnscrypt-proxy wasn't stopped before starting a new one, but I wouldn't know how to stop it, and I think the same thing is happening to @IntelligenceInside

systemctl stop systemd-resolved
and
systemctl stop systemd-resolved

but the response:

Failed to stop systemd-resolved.service: Unit systemd-resolved.service not loaded.
and
Failed to disable unit: Unit systemd-resolved.service does not exist

What solution is there?
