ok idk wtf happened... so:
I noticed yesterday there was a minor spelling mistake in the title of the original upload(uploaded for April Fools) so I tried updating it, I downloaded the updated chart and my game just crashed (which it never did before and I have almost 2k hours in it) then after re-launching it loaded normally and the audio and album art were missing from the chart
so I updated THAT and downloaded it again and the game crashed AGAIN and then re-launched with the chart missing audio and album art AGAIN. that cicle repeated a few more times and now I just completely re-made the chart
it's a new chart file (because clearly my game gets mad at me if I edit an existing one) so hopefully it fucking works now (if this isn't deleted by the time you're reading this then it most likely worked)

Anyway, this was uploaded for April Fools so just pretend the upload date still says April 1st. Thanks.
