Network Manager applet graphical bug

Hi, when I turned on my computer this morning I realized that the network manager tray icon was an earth instead of the “wired” icon. Whenever I click on the tray icon I get this error message :
Error loading QML file: qrc: /plasma/plasmoids/org.kde.plasma.networkmanagement/contents/ui/main.qml: 23: 1: plugin cannot be loaded for module “org.kde.plasma.networkmanagement”: Cannot load library /usr/lib/qt/qml/org/kde/plasma/networkmanagement/ ( Cannot open shared object file: No such file or folder )
Do you have any idea what might have happened? I’m a Manjaro newbie user.
Sorry for bad english, it is not my mother tongue.
