I've read all the corresponding threads and tried what had been described there, but still I am not able to launch my application after having packaged it with PyInstaller.

My platform is:

• macOS 12.5.1
• PySide6==6.3.1
• pyinstaller==5.3

When running my program (before packaging with PyInstaller) via

python main.py

everything works great.

I've created a .spec file for pyinstaller:

block_cipher = None


a = Analysis(
    ['main.py'],
    pathex=[],
    binaries=[],
    datas=[('ui_files', 'ui_files'), ('ExampleDatabase.csv', '.'), ('icons_rc.py', '.')],
    hiddenimports=[],
    hookspath=[],
    hooksconfig={},
    runtime_hooks=[],
    excludes=[],
    win_no_prefer_redirects=False,
    win_private_assemblies=False,
    cipher=block_cipher,
    noarchive=False,
)
pyz = PYZ(a.pure, a.zipped_data, cipher=block_cipher)

exe = EXE(
    pyz,
    a.scripts,
    [],
    exclude_binaries=True,
    name='Data Manager',
    debug=False,
    bootloader_ignore_signals=False,
    strip=False,
    upx=True,
    console=False,
    disable_windowed_traceback=False,
    argv_emulation=False,
    target_arch=None,
    codesign_identity=None,
    entitlements_file=None,
)
coll = COLLECT(
    exe,
    a.binaries,
    a.zipfiles,
    a.datas,
    strip=False,
    upx=True,
    upx_exclude=[],
    name='Data Manager',
)
app = BUNDLE(
    coll,
    name='Data Manager.app',
    icon='app_icon.icns',
    bundle_identifier=None,
)

then

pyinstaller 'app_packaging.spec'

When double clicking the executable 'Data Manager.app' in the list folder - it fails.
When running the app executable in the app contents setting the QT_DEBUG_PLUGINS=1 i get the following:

qt.qpa.plugin: Could not load the Qt platform plugin "cocoa" in "/Users/danil/Qt/6.3.1/macos/plugins" 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: cocoa.

[1]    5042 abort      ./'Data Manager'

I can see that the app cannot locate the libqcocoa, but the plugin is located inside the app bundle:

Could someone please help!
