Which of these network interfaces is the one created by incus init? On default it is named “incusbr0” but it seems like you have choosen a different name.
The default Incus network name is the one you should use to create your OVN network against and use it as the “UPLINK”. In short instead of using

incus network create UPLINK --type=physical parent=br1 --target=core

try to use:

incus network create br1 --target=core

Assume br1 is your uplink interface. This is how it is described in OVN high availability cluster tutorial. OVN need to know which is the uplink interface / network of your host. There is no such “UPLINK” interface on your host which results into the error:

@oddjobz

Could not load network state: Network interface "UPLINK" not found

Assigning the correct network interface during OVN network creation will solve the error.

That is at least the difference I can spot.
