VSCode extension debugging dont use the latest updated code

Question

I try to edit a vscode extension, update and add some customization, but when I debug it by pressing F5, my changes seem like not being executed. Even when I try to remove a piece of code that I am sure will break the extension, but unfotunately it still run like there are no changes at all. Am I wrong debugging it or there's caches that we should remove?

Btw I am using VSCode 1.52.1 on Ubuntu 18.04.

My launch.json:

{
    // Use IntelliSense to learn about possible attributes.
    // Hover to view descriptions of existing attributes.
    // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
    "version": "0.1.0",
    "configurations": [
      {
      "name": "Launch Extension",
      "type": "extensionHost",
      "request": "launch",
      "runtimeExecutable": "${execPath}",
      "args": ["--extensionDevelopmentPath=${workspaceRoot}"]
    }]
}
