Here's the stack trace with my name censored:

The issue was with a file without a line break at the end, I'm on windows so it has carriage returns too. Sometimes when I removed it, it stopped working, but it always worked with it in. Here's the HTML file (i was just messing around testing things)

<audio data-music id="freaky-menu" src="assets/music/freakyMenu.mp3"></audio>
<label><input type="checkbox">jefferys endless aethos</label>

My hunch is that this doesn’t have to do with your HTML file but rather your MP3 file, given the stack trace points here:

https://github.com/11ty/eleventy-dev-server/blob/f82a9b6922576a5d1f34bf7ed037e7abd0a41042/server.js#L542-L545

I did finally attempt to reproduce this with both a missing (and valid) MP3 file in both Chrome and Safari and wasn’t able to reproduce. I think we’ll need a repro test case to move forward here
