Reinstall / Configure Vmware tools and remove the VSS feature. You don't even have to perform a reboot and you will be able to take a snapshots again. Per: https://kb.vmware.com/s/article/1018194 "If you are using a third-party backup product that does not allow you to configure for non-quiescent snapshots, remove the VSS component from the Windows guest operating system, provided as part of VMware Tools. This results in VMware Tools attempting to use an older sync driver. When you request a quiescent snapshot, VMware Tools does not find and utilize the VSS driver and then attempts to quiesce using the sync driver. "
