SDK "Could not connect to Playdate Simulator" error

I’m trying to learn how to make games in the SDK, and just set it up recently, but whenever I try to run my code, I get the error "Could not connect to Playdate Simulator", and then it just doesn’t open the sim. Does anyone have any idea why this would be happening? I’m using Linux, Fedora 43, and am currently just trying to run the template project from SquidGod (for some reason it won’t let me link it).

The error popup and launch.json are pictured below (I haven’t edited the json file at all)

{
    "version": "0.2.0",
    "configurations": [
        {
            "type": "playdate",
            "request": "launch",
            "name": "Playdate: Debug",
            "preLaunchTask": "${defaultBuildTask}"
        }
    ]
}

SquidGod’s tutorial is a bit out of date at this point. This is the more current recommendation: https://www.youtube.com/watch?v=jD-KPMzT6po

ah, okay, thanks
