Audacity "fails to respond" when trying to import any file

I am trying to get a song I downloaded from Apple Music to load into Audacity (it has been converted from .m4p to .mp3 using TuneFab Apple Music Converter) and am constantly getting the swirling cursor. Any idea why this is? Any help would be appreciated.
