Denial of Service due to crash at initialization
I am using the latest version of the code add-in (0.6.7). I am editing a simple file: -module(test). -export([factorial/1]).
factorial(0) -> 1; factorial(N) -> N * factorial(N-1).
I have set the erlang path specifically to C:\Program Files\erl-23.2\bin.
When the system starts it displays the following in the output window. As far as I can see, this is an almost complete denial of service: Even though the colorizer does work, none of the commands do.

I have (always?) had more or less the same issue on MacOS with most of my projects. Erlang/OTP 24 installed via Homebrew.
A BEAM process is spawned that consumes 2 cores, which I need to kill manually.
Here is the Output panel from VSCode:
