Hyper-V Cluster issues

I had Windows Admin Center set up and working fine with a 2 node Server 2019 Hyper-V cluster, then back in July I upgraded the hosts to 2022 and had issues. I've had another go at getting this working but come stuck again. I've tried re-installing Windows Admin Center on a fresh 2022 host but it made no difference.

The issue: Dashboard shows 0 of 100% for the CPU usage (NaN% total) for the cluster, and for the memory usage just shows "of 0 B".

If I go into the "Virtual machines" page there are no results, but if I go into the VM summary page it shows me the graphs with total VMs, VM status, CPU, RAM etc fine. I am able to create a VM from the Virtual Machines page (confirmed by checking Failover Cluster Manager snap-in), but the list of VMs remains empty.

If I go into the Roles page, I can see all the VMs.

If I go into the Servers page, then Inventory, I see both hosts but uptime shows as 0 minutes, CPU usage "unknown" and Memory usage "unknown".

Spent most of the day trying to find anything useful online to no avail. It can obviously communicate with the cluster as it's able to create a VM, and see all the disk details, network traffic, and some of the host CPU/Memory details.

Both hosts running 2022 Datacenter on the latest updates.
