The ScPolicySvc service works by monitoring a specific registry key (See Deconstructing the Smartcard Removal Policy Service).
The VPN client (Connection Manager aka CM) on the other hand doesn’t use the Credential Provider architecture, it uses its own code for picking which certificate from the smartcard will be used for logon.
The VPN component not using CredUI or LogonUI has two side-effects:

But Smart Card Removal Policy service not start up ( on both computers )!
message : Smart Card Removal Policy service on Local Computer started and then stopped.
This sounds like you haven't set the ScRemoveOption registry key for the Smartcard Removal Policy service.
You need to set it to either (Lock/Logoff/Disconnect) if you want to use the service - see the link at the top of the page.
If the service starts up and finds that the registry key isn't set it stops again as it doesn't have anything to do in that case.
