Delphi RAD Studio 10 Berlin WebBroker HTTP Port error - no peer with the interface with guid

Question

I am using RAD Studio 10.1 Berlin, tried to create a REST sample application with following steps:

New Project->Select Other->Web Server Application->Standalone Application->VCL Application->Port Number.

I selected "Test Port" with 8080 and got this error:

No peer with the interface with guid {} has been registered.

I tried with different port number still got the same error.
