VMWare Workstation  "Transport (VMDB) error -14: Pipe connection has been broken."


I have an error "VMWare Workstation" and unable to boot virtual machines.

Error:    "VMWare Workstation    Transport (VMDB) error -14: Pipe connection has been broken."
VMWare Workstation version:   VMWare Workstation 15 Pro 15.5.1
OS:   Windows 10 Pro 64bit

After I upgrade VMWare Workstation 15 Pro from "VMWare Workstation", the error started appearing.
I deleted "lck" folder, but it did not work. I also created a new Virtual machine from OVF exported file., but then still the same error message popped up.

I need your assistance to solve this error message with detail step by step guidance.

The error started to be seen after upgrading the software to VMWare Workstation 15 Pro version. I did not see the error message with the previous version.

I deleted all of the virtual machines and also deleted ovf exported file I used for it.
Then, I copied them from the original source and created a new virtual machine again.
However, I still face the error message.

I think I would start by completely uninstall VMware Workstation Pro.

and after uninstallation reboot Windows OS.

Then re-install.

Create a quick virtual machine (no need to install an OS), just start the VM - does it start ?
