Apple Music audio stops when phone starts or ends the standby mode

Since the iOS 18 update, there's been a bug that always occurs when listening to music through Apple Music. When music is playing and the iPhone enters or exits standby mode, the music pauses by itself for 1 second. The initial conditions were the same as when this problem didn’t exist. I‘ve asked a friend and he said, that it does not happen on his phone. I am using an iPhone 12 Pro. When listening to music, I used Bluetooth headphones, but the same as when the problem wasn‘t there in IOS 17. Does anyone have the same problem and/or a solution?
