PyQt5 works but pyqt5.qtcore does not

When I import PyQt5 I get no errors but when I import PyQt5.QtCore pycharm does not make any errors just report this: Process finished with exit code -1073741819 (0xC0000005) this is because of qt. what I've done: I reinstalled pycharm and install and uninstall pyqt5 several times and I have no clue what should I do. I'm using windows 10

My import statement looks a little different than what you're describing. I usually see it like this

from PyQt5 import QtGui, QtCore, QtWidgets
