Unable to launch because of Qt Plugin

[temmeand]

I am unable to launch the app because of the error below:

$ doorstop-edit
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: xcb, minimalegl, minimal, linuxfb, vnc, offscreen, wayland-egl, vkkhrdisplay, wayland, eglfs.

Aborted (core dumped)

This has been observed on a few different computers. The latest one I tried was Ubuntu 22.04 with Python 3.11.

Any troubleshooting suggestions?

Not seen this before. Are you perhaps in some virtual environment?

Have you tried any solution suggested here or here?
