Hyper-V Checkpoint Error

I have been having an issue on a brand new Dell PowerEdge R650 that I loaded Server 2025 Standard on. I have also been having this same issue on servers loaded with Server 2022 as well. Whenever I attempt to create a checkpoint, I get the error:

When I check Event Viewer under Hyper-V VMMS, I am seeing the below Event IDs.

This problem goes away when I reboot the server, yet since these are Hyper-V hosts, that is not a viable option going forward. I need help to figure out what is going on.
