Internet no longer works after upgrade

The issue I am facing:
Upgraded from v5 to v6 and now nothing works. Websites dont load, apps wont work, etc…. I have had to remove pihole as my DNS from my router in order to use the internet.

Details about my system:
Raspberry Pi 4

What I have changed since installing Pi-hole:
Just upgraded from v5 to v6

Please upload a debug log and post just the token URL that is generated after the log is uploaded by running the following command from the Pi-hole host terminal:

pihole -d

or if you run your Pi-hole as a Docker container:

docker exec -it <pihole-container-name-or-id> pihole -d

where you substitute <pihole-container-name-or-id> as required.
