Seemengly randomly, but every day, bluez crashes and all bluetooth modules from Plasma disappear. The bluetooth icon doesn't show in the system tray, the Bluetooth KCM doesn't do anything when I try to turn on Bluetooth.

I think this is a dupe of 2397966
Yes, I have the same issue. The Bluetooth icon is appearing and disappearing, and I have similar logs in the system. My wifi/bt module: Qualcomm Technologies, Inc WCN785x.
