I have a similar issue, also on a lab machine. I have a fresh Windows 2025 Hyper-V host with Veeam 12.3 running on a Windows 2025 Guest VM, backing up about 9TiB to a new ReFS 3.14 volume (VHDX). After a few hours to a few days, the CPU usage spikes within the guest and requires a hard reset to get back up.
About a week ago, I created an identical VM with Veeam installed (with no backups configured), and it remains up.
