Scanning any Bluetooth Low Energy (BLE) device unexpectedly disconnects and unpairs my Bluetooth (Classic) mouse

[Abdull]

Describe the bug
Using toolBLEx version 0.12 from flathub (i.e., flatpak version of toolBLEx).

With toolBLEx, at the moment I select "scan device" / "scan services & data" / "scan services only" for a "Bluetooth: Low Energy" device, my connected Bluetooth ("Classic") mouse disconnects and unpairs. To have the Bluetooth mouse connect again, I have to go through an pairing phase again (press-and-hold button on Bluetooth mouse, pair mouse in my Debian 12 KDE Plasma wayland BlueZ GUI).

My Bluetooth mouse does not disconnect when scanning (and writing to) services and characteristics of BLE devices with gatttool and bluetoothctl.

Expected behavior
Scanning for services and characteristics of a BLE device, as well as interacting with them (e.g. writing data to a characteristic) shall not break / tamper existing Bluetooth pairings.

To Reproduce
Steps to reproduce the behavior:

1. In toolBLEx, select BLE device
2. With a BLE device selected/highlight, on the left, press the yellow-orange "scan device" button.
3. paired/connected Microsoft BluetoothMouse3600 disconnects (but e.g. paired/connected JBL Charge 2 speaker does not disconnect).
