Hello

Thank you for your question and reaching out. I can understand you are having issues related to Hyper-V VM checkpoint removal.

Based on your situation, it seems like the recovery checkpoints have been broken.

As far as I know, there is no way to delete the broken recovery checkpoints through the GUI or PowerShell.

Instead, you must manually merge them.

Please see the detailed steps below:

1.Please first Export the problematic VM for testing, then check in the location to ensure files are stored well.

2.Create a new test VM using the avhdx file which we exported on step 1 for below merging test.

3.For the new test VM, inspect the latest avhdxs, click ‘Inspect Parent’ to see their relationships until the last one with no more parent, that will be the original vhdx file.

4.Check the Checkpoint File Location, and go back to the Hyper-V manager console to Edit Disk:

5.Select the newest one first, then click merge; and then choose: To the parent virtual hard disk.

6.Repeat steps to fully complete the process of merging Hyper-V snapshot.
