Have you read about multi-target debugging and compound launch configs? https://code.visualstudio.com/docs/editor/debugging#_multitarget-debugging

@canvas-J I don't really understand what you are trying to do. Please provide exact steps for what you are trying to do, what do you expect and what is actually happening.

@weinand @Tyriar Thank you for your reply, here I made a . Obviously, I can only run one program under a single window. But before about two versions, I could run multiple programs in one window at the same time.

Basically 1.28.1 and earlier you could run multiple instances of the same program, but now you cannot. In my launch.json the following used to launch 3 servers and a master server, but any version after 1.28.1 it only launches 1 server and a master server

    {
        "name": "x3 launch all",
        "configurations": [ "server", "server", "server", "master_server", "client" ],
    },

A temporary workaround would be creating a bunch of launch configurations like server_1, server_2, server_3.. but this becomes impractical when you are doing stress tests with like 9 servers and a master server.
