Same problem here, except a new install of 24.04.1 but using the previous /home 
from 22.04. I can only get DNS working by manually adding a DNS entry (e.g. 
9.9.9.9) in /etc/systemd/resolved.conf. I've tried doing a --reinstall of the 
systemd-resolved pkg, makes no difference.
Here is output of "resolvectl status" with modified resolved.conf:
------------------------
Global
         Protocols: -LLMNR -mDNS -DNSOverTLS DNSSEC=no/unsupported
  resolv.conf mode: stub
Current DNS Server: 9.9.9.9
       DNS Servers: 9.9.9.9

Link 2 (enp5s0)
    Current Scopes: DNS
         Protocols: +DefaultRoute -LLMNR -mDNS -DNSOverTLS DNSSEC=no/unsupported
Current DNS Server: 192.168.1.3
       DNS Servers: 192.168.1.3

Link 3 (virbr0)
    Current Scopes: none
         Protocols: -DefaultRoute -LLMNR -mDNS -DNSOverTLS DNSSEC=no/unsupported
-------------------------

The Link2 DNS entry is correct, that should work by itself, and it
does/did work before 24.04 (when it was eth0 not enp5s0). However I
don't know this systemd-resolved stuff at all.
