metadata was found in the file but it is corrupted and could not be read

I recorded a DJ set using an RCA to XLR cable going from the mixer to a zoom H6 field recorder, and the file opens in Adobe audition but it gives me this message when I open it up "metadata was found in the file but it is corrupted and could not be read"

when I click "ok" I can see the file and the waveforms but there's a buzzing sound in the track and it's definitely not sounding as clean as it's supposed to. Any thoughts as to how I could fix this?

I attached a sample clip from where you can hear the buzzing.
