To help us to debug the issues, could you pls help to provide following information:

    1. WS build
    2. Detailed steps about how to reproduce this issue
    3. ui log (should be under %TEMP%, you can get detailed log location under "Help > About VMware Workstation ")
    4. vm related log file, you can get the vm log file location by choosing the VM within VM library, then check "Help > About VMware Workstation".

        if there is a vm crash, there should be also *.dmp, *.corez file under the same location as vm log file, pls collect them as well
