[SOLVED] Cannot start any application until restart.

This problem occurs at random and I cannot start any app until I restart Artix.
When i try to run nano or dolphin a get same error.
Code: [Select]
kstart plasma-desktop
plasma-desktop: no process found
Invalid MIT-MAGIC-COOKIE-1 key
qt.qpa.xcb: could not connect to display :0
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, wayland-egl, wayland, wayland-xcomposite-egl, wayland-xcomposite-glx, xcb.

Unfortunately it did not work for me.
What I recognized that it probably is some issue with network because when I disconnect my smarthone which I tether internet through suddently I can start applications..

I still think it's probably the hostname
Run the command
Code: [Select]
hostname
both before and while tethering your phone. If the output changes that's your problem.

What network software do you use to handle the tethering of your phone?
