Windows doesn't see installed PyQt5 module?

Question

Python

Good afternoon everyone,
please help a newbie to solve this problem:
I installed the PyQt5 module via pip install
at the beginning of the program imported modules:
import sys
import time
from PyQt5 import QtCore, QtGui, QtWidgets
from interface_timer_2 import *

but the program does not work when running the code from pycharm
in the console the following message appears - Process finished with exit code -1073740791 (0xC0000409)
and windows 10 gives such an error

, and this is on a laptop, on a stationary computer with the same Windows 10, there is no such error,
I screwed something up here, and what not can understand....

Set this variable

QT_QPA_PLATFORM_PLUGIN_PATH="C:\Python33\Lib\site-packages\PyQt5\plugins\platforms"
