Well, you can select which libraries shall be compiled. If you are not debugging the CSV library, just compile it: [Debugging · Julia in VS Code](https://www.julia-vscode.org/docs/stable/userguide/debugging/#Settings-to-speed-up-the-debugger)

You can also try [https://plugins.jetbrains.com/plugin/29356-flexible-julia](https://plugins.jetbrains.com/plugin/29356-flexible-julia), which is a commercial offering, so you need to pay for it unless you work at a university. On the other hand, if you have a bug report or feature request they address that very fast.
