Never had to uninstall Unlocker. Always reinstalled it after a VMware Workstation new version update, yes.
And I also recently learned to Shut down all macOS VMs too, then update VMware Workstation from older to newer version, to avoid possible VMs failure issues.
(no issues like this with my 2 Windows VMs on that PC, so those I just leave as is - i.e. Saved/on Standby).
