FL -> Cubase Bass crackling problem

When i export an .wav instrumental in FL Studio and drag it into Cubase to record vocals, the bass in the instrumenal is crackling severely. When i export the Cubase file, the bass crackling remains. When i open it via the media player on my pc, there seems to not be a problem so it can’t be an FL Studio failure .Thanks for reading. I hope somebody is ready to help me out. :smiley:
