I'm having the same problems. it got to the point it crashed my PiHole last week. Here is my debug token is: https://tricorder.pi-hole.net/2w8IGhWB/
Please help!
You have configured your Pi-hole with eth0 on 192.168.1.3/24.
Also your router uses the 192.168.1.0/24 subnet

Do you have any idea where the queries from the 192.168.254.0/24 subnet might come from?

Do you use a VPN?
Yes, I know know exactly where 192.168.254.0/24 comes from, they are all Amcrest devices. I tried to separate these devices from my regular traffic.
I have do use a VPN when I want to RDP in to my network but I do not use VPN from the network for outbound traffic.
How do you suggest I configure it? Any suggestion would help. Thank you.
Should these devices use Pi-hole as DNS server? If so, you need to set "Settings/DNS/Interface settings" to "Permit all origins". If not, let them use the router as DNS server.
Actually I don't want these devices to reach the internet, I've even removed the removed the DNS IP address in the devices configuration but for some reason it's still causing problems but I'll just change the settings to "Permit all.."
