Hi, after the latest updates, I noticed that the Bluetooth icon on the dock disappears and reappears intermittently. My log shows lots of entries:
11:25:19.027 UTC dbus-broker.service A security policy denied :1.40 to send method call /midi/profile:org.bluez.GattProfile1.Release to :1.76.
wifi/bt chip: Network controller: Qualcomm Technologies, Inc WCN785x
I have the same thing happening, starting in the past few days. If I check logs under dmesg, there are many instances of this:
[10116.421509] usb 1-6.4: USB disconnect, device number 51
[10118.273103] usb 1-6.4: new full-speed USB device number 52 using xhci_hcd

This is using a generic Bluetooth 5.3 USB dongle.
Edit: the messages are the same, except the USB device number increments each time.
Two reports about this bug are already on Red Hat Bugzilla.
It seems to be specific to Fedora with KDE (KDE 6.5.4). I don’t see it on openSUSE Tumbleweed (KDE 6.5.4).
