I’m on a Mac and this worked for me! THANK YOU
Bambu needs to give us a more human readable error message instead of this cryptic nonsense:
Player is malfunctioning. Please reinstall the system player. [2:2] <02-02 11:02>
Worked for me. Thank you! 
Seems to be fixed now with the update of BambuStudio 1.10.2.76 on macOS. Good job, Bambu Lab!
Had the same issue, did the media player install even B studio. This is a new PC for the printers only. The camras were working fine in LAN mode. then nothing, error 2:2. finally figured it out. the video must use a different protocol than TCP likely UDP on the private LAN. I could conect see status and even send prints, just no video. I am very paranoid with the increase in cyber attacks and use a VPN most of the time, and once I turned it off, instant connected video. does anyone know the port number off hand the video uses?
