Enabling CPU compatability mode in Windows Server 2025 crashes the VM.

My Hyper-V cluster is Windows Server 2019. I've tested the same VM in my test cluster, which is a Windows Server 2022 Cluster, and it works without any issue even after the CPU compatibility is turned on.
Does this mean Windows Server 2025 is not working in Windows Server 2019 Cluster while the CPU compatabality is turned on?
