After starting named with my named.conf.options setting, I manually generated virbr0 with brctl and set the IP address (192.168.122.1), and named started listening to 192.168.122.1 using TCP.

Because of this behavior, I think that the operations of dnsmasq and named conflicted, resulting in an error on the dnsmasq side(the second make_sock() with SOCK_STREAM).
This named is started because it is necessary, but I understand that the VM host should not run many processes, so the name resolution function is not run on the VM host, but on another I'm planning to move to a server.
I understood where the problem is. Thank you very much for your cooperation.
I initially reported it as a bug in dnsmasq, but it turned out to be a problem in my environment.
