Since the update to PyCharm 2019 I am unable to load the QGIS Python modules.
I can not use auto completion either.
I already deleted the cache (by invalidating the cache in PyCharm and also by deleting the "system" folder in the user settings directory), nothing seems to work.

When starting the Python console inside of PyCharm and typing "import qgis.core", I get the following error:

Traceback (most recent call last):
 File "<input>", line 1, in <module>
 File "C:Program FilesJetBrainsPyCharm Community Edition 2018.2.2helperspydev_pydev_bundlepydev_import_hook.py", line 21, in do_import
 module = self._system_import(name, *args, **kwargs)
 File "C:OSGEO4~1appsqgis-ltrpythonqgiscore__init__.py", line 27, in <module>

ImportError: DLL load failed: Das angegebene Modul wurde nicht gefunden.

Something seems to be broken, in PyCharm 2018.3 everything was ok. The sys.path environments and interpreter settings seem to be correct:

['C:\Program Files\JetBrains\PyCharm Community Edition '
 '2018.2.2\helpers\pydev',

Has anyone updated PyCharm to 2019 and can confirm this?
I also reinstalled the whole QGIS installation, but nothing seems to work.

It looks like the DLLs containing the stubs are incompatible now?

My bat for starting PyCharm looks like this:

@echo off
SET OSGEO4W_ROOT=C:OSGeo4W64
call "%OSGEO4W_ROOT%"bino4w_env.bat
call "%OSGEO4W_ROOT%"appsgrassgrass-7.4.2etcenv.bat

I use such *.cmd file (different than yours) to start PyCharm. Try to use it.

@ECHO off

I have the same issue :

from PyQt5 import QtGui, QtWidgets, uic
ImportError: DLL load failed: Le module spécifié est introuvable.
from qgis.core import QgsVectorLayer
ImportError: DLL load failed: Le module spécifié est introuvable.

My configuration :
QGIS version 3.4.6-Madeira
PyCharm Community 2018.3

My .bat to run PyCharm :

@echo off

SET OSGEO4W_ROOT=C:Program FilesQGIS 3.4
SET PYCHARM="C:Program FilesJetBrainsPyCharm Community Edition 2018.2.6binpycharm.exe"

SET QGIS_PREFIX_PATH=%OSGEO4W_ROOT%appsqgis

start "PyCharm aware of QGIS" /B %PYCHARM% %*

Any idea ?
