qt.qpa.xcb: could not connect to display
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, minimal, minimalegl, offscreen, vnc, wayland-egl, wayland, wayland-xcomposite-egl, wayland-xcomposite-glx, xcb.

Have you found any solution ?

After a while of searching, I finally understood the reason and how to fix it

As detailed from the error message, it spits out that xcb couldn't be loaded for whatever reason
XCB is a library implementing the client-side of the X11
Basically meaning, you can't launch it because it can't connect to your X server for some reason

As it details:

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

This means that we can use plugins aside from xcb which would be eglfs, minimal, minimalegl, offscreen, vnc, wayland-egl, wayland, wayland-xcomposite-egl, or wayland-xcomposite-glx

You might need to play around with it but I noticed that offscreen and wayland work well for me

So to change this, write flatpak override --user --env=QT_QPA_PLATFORM=xcb org.torproject.torbrowser-launcher into your terminal where you change xcb with whatever other plugin you'll use instead like offscreen or wayland
