Occasional blocked DNS traffic for (seemingly random) single device

Since upgrading to 23.1.*, I've been having an odd issue that I can't seem to figure out the source. Occasionally seemingly at random the firewall will start blocking Port 53 DNS traffic, sometimes if I let it sit for a few moments it will correct itself, other times it requires a reboot. Usually only affects a single device in a single VLAN. I don't see any errors in Unbound logs or the Firewall logs. I can however see the blocked packets. I've attached a during and after screenshot of the logs as well as the DNS rule for that VLAN (it does affect other VLANs as well).
Hopefully someone has some idea what is causing this issue. I'm not sure what changed during the upgrade but it is new since then. If there is any other info I can provide please let me know.
