Pihole should be able to make DNS requests from itself and its OS.
I have it setup using DoH and all clients are working normally and can browse the internet using DNS names and 1.1.1.1/help also states DoH is working.
The setup is fairly new and all clients are clearly working and dns is resolving by pihole so this all good.
Actual Behaviour:
Pihole not able to resolve DNS names itself, meaning I can ping 8.8.8.8 from pihole console but I cant ping google.com, so piholes own resolver is for some reason not working. Do not know why this is happening.
Any ideas?

Pi-hole does not touch the DNS configuration of the host it runs on.
It is recommended to use at least one public DNS resolver for the host, so you would still be able to do updates and run fixes in the event of Pi-hole being inoperational.
Your debug log suggests you did configure your host OS to use 192.168.1.5 for DNS:
You'd have to address your issue by adjusting that machine to accept and answer DNS requests.
Alternatively, if you no longer want your host to use 192.168.1.5 for DNS, you'd have to change the DNS configuration of your host OS.
It would depend on your host OS how you do that.
For RPi OS 11 (as shown by your debug log), that would most likely involve either editing /etc/dhcpcd.conf or configuring NetworkManager.
