Bug opening

[YasminaBrioaGil]

I downloaded the software in my Debian 12. When I execute it with "python3 -m qualcoder" the window is opened, but once you click anywhere it disappeares and show the following message in the console:

qt.qpa.wayland: Ignoring unexpected wl_surface.enter received for output with id: 7 screen name: "Screen5" screen model: "unknown" This is most likely a bug in the compositor.
qt.qpa.wayland: Ignoring unexpected wl_surface.enter received for output with id: 7 screen name: "Screen5" screen model: "unknown" This is most likely a bug in the compositor.
The Wayland connection broke. Did the Wayland compositor die?

I attach image.

This could be hard to fix. Linux desktops use different windowing display systems: wayland, xwayland, x11. Some of these systems do not always work so well with the Qt graphical display that QualCoder uses.
You could try this starting command below, (I read it from here https://avidemux.org/smif/index.php?topic=20527.0)

python3 -m qualcoder --platform 'xcb'

Other possibilities, these are guesses only:
1 Is your Debian updated regularly?
2 Would a newer Debian version be better? e.g. Debian 13?

I just updated today Debian. May be it is because I have Python 11 because my Debian 12 isn't able to install the 12th version. I put the code you suggested and this is what appeares now:

"qt.qpa.plugin: From 6.5.0, xcb-cursor0 or libxcb-cursor0 is needed to load the Qt xcb platform plugin.
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, vkkhrdisplay, vnc, wayland-egl, wayland, xcb.

Aborted (core dumped)"

What could I do now?

Thank you for your help and time.

I am running out of ideas.
This is something Bing copilot found which might fix the xcb platform:
However, this is also risky, because it will add or update these files within your main Debian system. This means that while your computer will likely work normally, there is a possibility it may not. So only you can decide to proceed.

sudo apt-get install libxcb-xinerama0 libxcb-icccm4 libxcb-image0 libxcb-keysyms1 libxcb-render-util0
