Wish I had more info to put here, like exactly what instrument it was, but I can’t access the track whatsoever. It’s also impossible to navigate the site once this popup appears because it will continue to pop up until you close the browser tab or refresh the page.
Hey @liamCorbett, sorry about this, it looks to be related to our new sound library. I’ll look into this and get it resolved, can you you email me (ryan(at)hooktheory.com) the name of the song that’s doing this?
EDIT: Figured out what was causing this, will get it fixed shortly
EDIT: This issue will be fixed in 2.12.4, which we will push shortly.
