-- Information about the crash:
I've just setup a new bluetooth mouse and keyboard device (Logitech MX Mechanical Mini for Mac, don’t ask why for Mac, hah) and right after setup and trying out a few of the function keys, KDE Connect crashed multiple times.
KDE Connect has the bluetooth and wifi backend enabled and is paired with my Android phone. I don’t know if there was a bluetooth connection between my phone and my PC but there was a wifi connection available and both seemed to be connected via that.

The reporter is unsure if this crash is reproducible.
