Why does LG Airplay always show busy status?

[AC Question]

I have a latest LG G4, dual SIM version. I use LG Bridge on my laptop and connect LG Airplay on my phone. I do get the connection and can browse all files of my phone on my laptop. But data backup and software upgrade tabs always flash "Airplay is busy" error. Why?
