Hyper V Orphan Checkpoint

Hi,

I have a simple setup as follows:  
- 2 clustered Hyper-V hosts  
- 1 clustered VM with its VHDX stored on central shared storage  

After a network disruption, the VM was improperly shut down. Following that, I noticed a checkpoint was automatically created. However, in Hyper-V Manager, the checkpoint has no “Delete” option to merge it back into the main VHDX file.

Here’s what I’ve tried so far:  
1. Powered off the VM.  
2. Edited the disk and manually merged the AVHDX back into the VHDX.  
3. Reconfigured the VM to use the merged VHDX file.  

The VM can now power on normally without issues.  
However, the “orphaned” checkpoint still appears, and I am unable to perform a Live Migration between hosts.  

I’ve also attempted to remove the checkpoint using PowerShell (`Remove-VMCheckpoint`), but it failed.  
I need assistance on how to properly clean up this orphaned checkpoint so Live Migration will work again.
