this is just a bit related to veeam, as it is a Hyper-V problem created by Veeam.
I have some VM's running on a 2012R2 and on a 2016 Hyper-V Cluster, that cannot delete the Checkpoints (for whatever reason, that's another thing to tackle).
I see the checkpoints in the Hyper-V Manager, but I cannot delete them, see picture: https://ibb.co/kyssFbj
Now I manually merged the checkpoints into the original VHD and told the VM to take the merged VHD as a drive (as it had the checkpoint mounted) and the VM starts without a problem.
I still see the checkpoints as they are in the picture, still cannot delete them (when deleting with powershell it's the same issue)
The problem is, that the Hyper-V manager still has those Checkpoints referenced somewhere and that reference didn't get deleted, when I try to delete it just tells me that the corrosponding file cannot be found (yeah no sh*t, I merged it

Does anyone have a better solution to this than creating a new "empty" VM and mount the merged VHD to that VM (then configuring the Network).
There needs to be a better way, but I cannot find anything online, all the "manually merge VHDX drives" manuals end with the merge without looking at the Hyper-V Manager.

Same problem without solution
