One AirPod creating static, but only in a specific iOS GarageBand project.

I was quickly throwing together a composition in GarageBand on my iPhone 13, like I often do, when suddenly my left AirPod (third generation) broke out into very loud static as I played the project back. Disconnecting and reconnecting did nothing. After some messing around, I found that it only created the static when one specific guzheng track was playing — the minute I muted the track, the static went away. Lowering the guzheng’s volume didn’t stop the static, nor did panning the guzheng all the way to the right (as it was the left AirPod). Muting tracks other than the guzheng didn’t make the static cease, either — it only relented if the guzheng track was muted. Additionally, when I opened up a different project I used the guzheng in, the AirPod behaved. No static at all. This different project also had far more tracks and reverb to it than the first one did, so I can’t imagine that either of those factors would be the cause. What I was doing should not have caused the audio to be overdriven, but I can’t find any other reason why it would break out into static in such a weirdly specific situation. If anyone has an idea as to what’s happening, I’d much appreciate it. Thanks!
