Zombie process when command exits > 0

[cartok]

Hi, today my CPU was suddenly going crazy, and it would not stop. The command which caused it was .vscode/extensions/tetradresearch.vscode-h2o-0.2.15/out/../bin/h2o-x86_64-unknown-linux --command /usr/bin/starship --format json. I disabled the extension, but it still ran. I uninstalled it and still my VS Code tries to execute it when I reload it.

❯ /usr/bin/starship --format json
error: unexpected argument '--format' found

Usage: starship <COMMAND>

For more information, try '--help'.

NOTE:
    passed arguments: ["--format", "json"]

❯ echo $?
2
