Failed to power on virtual machine Win10_Utility_7-2-18_OLD. File system specific implementation of LookupAndOpen[file] failed Click here for more details.

Any ideas what this error is?  I recently moved this VM from one ESXi server to another using the vCenter Converter Standalone (as I've done for several other VMs-succesfully).  I get this popup when I try to power on the VM

thanks,

Greg
