Application: plasmashell (5.19.5)
 (Compiled from sources)
Qt Version: 5.15.1
Frameworks Version: 5.73.0
Operating System: Linux 5.8.17-300.fc33.x86_64 x86_64
Windowing system: X11
Distribution: Fedora 33 (KDE Plasma)

-- Information about the crash:
- What I was doing when the application crashed:

Everytime I tried to connect my laptop to internet using wifi, right after I click the wifi icon on the panel, my laptop didn't respon anything and suddenly becomes blank (black screen) for about 5-10 seconds and then an error notification appears. Sometimes the blank/black screen doesn't recover and I have to manually restart it using the power button.

P.S. My laptop merk is Asus X450C. And there is no problem if I connect my laptop using method "wired connection." I'm using Fedora KDE Plasma as my distro.

Thank you, I hope you understand what I'm trying to explain.

The crash can be reproduced every time.
