Application: kdeconnectd (21.12.3)

Qt Version: 5.15.3
Frameworks Version: 5.92.0
Operating System: Linux 5.13.0-37-generic x86_64
Windowing System: X11
Distribution: KDE neon User - 5.24
DrKonqi: 5.24.3 [KCrashBackend]

-- Information about the crash:
- What I was doing when the application crashed:
I started my computer and logged into my user account.
Almost every time I start my computer and log into my account, KDE Connect reports an error. Subsequent attempts to connect to the phone are now successful. Until the computer restarts again. The fault does not happen all the time, but very often.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Usługa KDE Connect (kdeconnectd), signal: Segmentation fault
