On FreeBSD, the simple default answer to the OP subject is...

Attempt to undo at least some of whatever unknown things you were
trying to do thus hopefully restoring the system back to the install
defaults provided in base.txz of the latest release...

rm /etc/resolv.conf
rm /etc/resolv.conf.bak
rm /etc/resolvconf.conf
rm -r /var/run/resolvconf

And let the system do it...

/etc/rc.conf.local:local_unbound_enable=YES
reboot

If your interfaces are managed by dhcp / rtsold / vpn,
see the manpages: resolvconf, dhclient, rtsold, openvpn

And even things like this if still needed...
chflags schg /etc/resolv.conv
