I'm running VMWare Workstation 14 on a Windows 10 laptop with a CentOS guest.

I have been struggling with intermittent problems when returning to the laptop and entering my password to unlock the host OS that the virtual machine seems to be frozen. It seems to be a little unpredictable, normally it will get stuck showing the last thing that was displayed on the screen but sometimes it gets stuck showing the guest OS welcome screen or a black screen.

Sometimes it freezes itself after a short time, say 30 sec - 1 minute, but sometimes it takes much longer than that - even 15 minutes occasionally. And some of the time it doesn't happen at all. Whenever it does happen, normally once the virtual machine starts responding again the display flashes as if to suggest that the window manager or some other component of the GUI has restarted, and there is a pop-up notification to say that systemd (or something like that will edit later with exact name) has crashed.

I also had this problem using Workstation 12, but it seems to have got worse (i.e. takes longer to respond) since upgrading to Workstation 14.

Any ideas how to troubleshoot this please?
