Toggle Breakpoint does not work in Visual Studio Code - visual-studio-code

Question

When I try to set a breakpoint nothing happens; I put my cursor on the println! line and press F9.
fn main() {
println!("Hello, world!");
}
I works on another machine where Visual Studio 2017 is installed, so I suspect this might the problem.

I have Visual Studio 2019 installed:
>cl --version

I have these Visual Studio Code extensions installed:
C/C++ 0.22.1
Rust (rls) 0.6.0
I am using Rust 1.33.0.
