PyQt5 can't find DLL

[Andreas Müller]

I'm running qgis-ltr 3.22. When I try to import from PyQt5, I get the error below:

    from PyQt5.QtCore import QSettings
    Traceback (most recent call last):
       File "<stdin>", line 1, in <module>
    ImportError: DLL load failed while importing QtCore: Das angegebene Modul wurde nicht gefunden.

May be I'm missing something, so I can't find QtCore.dll in my install for example.

Not reproducable here. The QtCore module file is called QtCore.pyd and the corresponding Qt DLL Qt5Core.dll

If I use the Python Console inside QGIS, it works, calling python-qgis-ltr.bat on the OSGeo4w-Shell I get the error. PATH and variables all look fine.

Still can't reproduce. Running python-qgis-ltr.bat from OSGeo4W shell in a fresh install of qgis-ltr:

run o-help for a list of available commands
C:\OSGeo4W>python-qgis-ltr
