I am trying to run my PySide6 Python application on an Orange Pi 3 LTS running Armbian, but while the app seems to start, the GUI is not visible.

I get the following error:

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 plugin does not support propagateSizeHints()

What I've tried:

• Installed libxcb-cursor0 using:

  sudo apt install libxcb-cursor0
  

  but it did not resolve the issue.

• The app runs inside a virtual environment (.env)—could this be causing the problem?

• I reinstall pyside6 and updated pip and nothing

How can I resolve this issue and make the GUI visible? Any help would be appreciated!
