Workstation 12 Pro UI crashes leaving VMs running but with lock files

This is not a fatal problem but it is really annoying.

Running VMware Workstation 12.1.1 Pro on Windows 10 pro version 1511

What's maddening is that I just purchased this upgrade February 1, 2016, but I am not allowed to file a support ticket online.

This first happened with Workstation 10 on this system but has recently returned.
If I leave the GUI running for too long - like over night - I see a crash the next day.


After clicking OK, the GUI is gone but the VMs are still running just fine.

If I find and delete all the .lck files in the VM's location on disk, I can open the GUI again to view the console of any running system.

You would think the specificity of this error would make it easy for a developer to find!

Here is the version information from the About dialog:20160503-Workstation12-About-Dialog-redacted.png

EE and programmer before UNIX existed.

Hi lcbrevard2012,

Thank you very much for using Workstation. Could you please let us know if this workaround(adding 'C:\Program Files (x86)\VMware\VMware Workstation' to defender exclusion list) works?
