Today I received VMWARE Workstation Pro 15.5.6.
I am still running openSUSE LINUX Version 15.1. as host system. I cared about, that every available update of openSUSE has been installed before trying to install VMWare Workstation 15.5.6 on the host system. The installation process itself runs without error messages.
However still unfortunately the result is, that I am unable to start my virtual machines. When testing to start the (suspended) Windows 10 virtual machine, I get the message:
Unable to change virtual machine power state: Transport (VMDB) error -14: Pipe connection has been broken.
when I start to resume the virtual machine.
Being cautious from my last tries to install VMWARE Workstation Pro 15.5.5 (which failed) I used my test Linux machine for installation only. I still may resume the virtual machine using Workstation 15.5.2
