Bug 423468

Application: systemsettings5 (5.18.5)
 (Compiled from sources)
Qt Version: 5.15.0
Frameworks Version: 5.70.0
Operating System: Linux 5.7.0-3-MANJARO x86_64
Windowing system: X11
Distribution: Manjaro Linux

-- Information about the crash:
When I tried to Click "application style" and select application style, the system settings crashed. I think this is probably because I used some themes that I downloaded from the KDE store. My plasma is 5.18.5.

The crash can be reproduced every time.

-- Backtrace:
Application: 系统设置 (systemsettings5), signal: Aborted
Using host libthread_db library "/usr/lib/libthread_db.so.1".
