Python APPCRASH while opening WebCam

I have successfully installed opencv-python.I wanted to open webcam for capturing video using python.But whenever I run the program in PyCharm console the webcam opens with fuzzy frames and Python stops working instantly showing the message:Python Appcrash access violation error and PyCharm console shows the message "Process finished with exit code -1073741819 (0xC0000005)"

The code is as follows:

import cv2
cap=cv2.VideoCapture(0)
while True:
    ret,frame=cap.read()
    cv2.imshow('frame',frame)
    if cv2.waitKey(10)==ord('q'):
        break
cap.release()
cv2.destroyAllWindows()

Why this problem occurs and how to solve this?

My Windows Version: Windows 7 Professional

Python Version: 3.7

opencv-python version: 4.3.0.36
