[SOLVED] My computer can't open any apps with WiFi connected

If my computer is connected to the internet, it will not open all the apps
This is a video I recorded when the crash occurred；https://www.bilibili.com/video/bv1cD4y1q74e
The result that occurs when the command line starts the graphical app
Authorization required, but no authorization protocol specified

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.

Most likely you have not set a hostname.  Post the output of each of the following from before and after connecting to wifi:

cat /etc/hostname
hostname
hostnamectl
