Failed to Start Virtual Machine in VMWare Workstation Player

I upgraded VMWare Workstation Player to 15.5.2 on a Windows 10 host. It failed to start any virtual machines after the upgrade. The error message is

VMware Player and Device/Credential Guard are not compatible. VMware
Player can be run after disabling Device/Credential Guard. Please visit
http://www.vmware.com/go/turnoff_CG_Dg for more details. 

I followed the instruction to make sure that the Device Guide was disabled. Since I have a Windows Pro, to disable Device Guard, I run the Local Group Policy Editor

mmc gpedit.msc

However, the problem remains. It turned out an additional step was need, that was to run the following command as the system adiministrator and reboot the Windows host,

bcdedit /set hypervisorlaunchtype off
