Pycharm crashes when running a basic opencv script

When I run this script, Pycharm gives an error and crashes.

Script - 

import numpy as np
import cv2

cap = cv2.VideoCapture(0)

while(True):
    # Capture frame-by-frame
    ret, frame = cap.read()

    # Our operations on the frame come here
    gray = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY)

    # Display the resulting frame
    cv2.imshow('frame',gray)
    if cv2.waitKey(1) & 0xFF == ord('q'):
        break

# When everything done, release the capture
cap.release()
cv2.destroyAllWindows()

Error - Process finished with exit code 134 (interrupted by signal 6: SIGABRT)



The script runs perfectly in VSCode though
