PowerShell Tool Remote Session failed on Visual Studio 2019

I am trying to use PowerShell Tool in Visual Studio 2019 (v. 16.6.3) to debug PS codes. When I tried to start a remote session in PS Interactive Window I got the following errors (even though I was able to do the New-PSSession on the remote server using separate PS terminal:
[ERROR] Enter-PSSession : You are currently in a Windows PowerShell PSSession and
[ERROR] cannot use the Enter-PSSession cmdlet to enter another PSSession.
[ERROR] At line:1 char:1
[ERROR] + Enter-PSSession -ComputerName myserver -Credential ‘’
[ERROR] + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
[ERROR] + CategoryInfo : InvalidArgument: (:slight_smile: [Enter-PSSession], Argument

[ERROR] + FullyQualifiedErrorId : RemoteHostDoesNotSupportPushRunspace,Microsoft.P

Any suggestions?
