Just wanted to share here since I know lots of folks use NUC or similar small form factor machines running N5xxx series Intel CPUs and proxmox. Since around the June timeframe with Proxmox 7.2 switching to 5.15 kernel, there have been instability issues for VMs. These appear to be getting addressed with future 5.19 kernel update, but might also require you to apply latest microcode updates as well to your proxmox host.
In my case running on an N5095, I had been dealing with this for sometime, unable to pinpoint cause of the HASSOS hangs, which have gotten worse and worse, to never run more than a 24 hour period. I was able to migrate the VM to a xeon proxmox host, had no issues, and I came across this proxmox post with lots of non-HassOS VM’s have similar problems - VM freezes irregularly | Proxmox Support Forum
