The main reason for a player entering an emergency loop is that it did not receive the expected data stream for the song it was playing. If the source is connected to the USB port, then it could be a faulty USB port, low-performance USB drive, or corrupt file. If the error occurs when the player is linked and the source is another player, then the issue could be the ethernet jack on either device, the network cable, if used - the network switch / router, or the same USB items per above. If linked to rekordbox, the issue could be a firewall, network sharing application blocking traffic, antivirus / antimalware software, or a virus or malware infection.
