We should check HResult -2147024713 (800700B7) here: https://github.com/PowerShell/PowerShell/blob/618d1a7c78f0702156d5ba1cd1be31df6d7f54d7/src/System.Management.Automation/namespaces/FileSystemProvider.cs#L6120-L6122

Some of my older scripts that relied on Move-Item to merge some directories stopped working after I updated to 7.3. I’m pretty sure they used to work fine until around 7.2.7 (I used them for the last time around Nov 22)
