No Wifi and Bluetooth in system tray (KDE, Manjaro)

As the title says, the wifi and bluetooth symbol wont show up in my system tray after i reinstalled my distro. I already found out that i had to manually install plasma-nm but even after that it didnt work. Both things work fine inside the live-usb and on Windows, so i can rule out any hardware issues.

Here you have the outputs of lspci, ifconfig and iwconfig:
