I’m encountering an issue with my Qt application on macOS. When I try to run my PySide6-based application, I get the following error:

qt.qpa.plugin: Could not find the Qt platform plugin "cocoa" in ""
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Steps I’ve tried: • Reinstalled PySide6 using pip install --force-reinstall PySide6. • Checked for the presence of the libqcocoa.dylib plugin in the PySide6 installation directory, but it seems to be missing. • Set the QT_QPA_PLATFORM_PLUGIN_PATH environment variable manually to the platforms directory, as shown below:

import os os.environ["QT_QPA_PLATFORM_PLUGIN_PATH"] = "/path/to/PySide6/plugins"

•   Tried running the app from the terminal after manually setting the path, but the error persists.

Environment: • OS: macOS (Version 15.3.1) • Python Version: 3.11.11 • PySide6 Version: 6.8.2.1

Question: • Is there something I’m missing in my setup? How can I resolve the cocoa platform plugin issue? • What should I do if the libqcocoa.dylib plugin is present in the PySide6 platforms directory?

Any guidance or solutions would be greatly appreciated!
