tldr: if you really want this purified you should probably just redo it from scratch

• The audio file is too high bitrate, it can't be higher than 192kbps
• Videos must not contain an audio track. You'll have to remove it with an external program

Mapping:

• Your tempomap is basically entirely wrong, the BPM should be 235. Because of this most notes are off sync, also causing weird patterns and rhythms that really shouldn't be there
• The part at 34875 scrolls too fast
• The patterning in the parts at 140875 and 157250 is a bit strange. It feels like you just put random chord sizes instead of matching the song
• There's also some ghost notes that don't feel matched to anything throughout (for example 71875)

I'm not gonna go too deep into mapping issues since the tempomap problems require what is basically a total rework, but I do recommend joining the discord to ask about stuff and getting mapping advice
