USB Webcam does not work in the newer version: 4.7.0.72

USB Webcam does not work in the newer version: 4.7.0.72

I wrote a simple script to read frames from a webcam, it works fine with laptop-attached webcams. When I try to use with the USB-based webcam (not-branded webcam), it returns the following error.

[ WARN:1@2.601] global cap_msmf.cpp:1759 CvCapture_MSMF::grabFrame videoio(MSMF): can't grab frame. Error: -2147024809

My Code:

import cv2


cap = cv2.VideoCapture(2)

while True:

    
    ret, frame = cap.read()
    

    if ret:

        cv2.imshow('Input', frame)
    else:
        print("dsd")

    c = cv2.waitKey(1)
    if c == 27:
        break

When I install the older version of OpenCV-python: 4.5.5.62, it works fine, I think the issue is with the newer release.

Please take a consideration on it.

Start by reproducing the supplied cv2.VideoCapture(2) script with the USB webcam on OpenCV-Python 4.7.0.72, then compare it with 4.5.5.62. Investigate the MSMF grabFrame warning and determine the cause of the version-specific failure; done means USB webcam frames are read successfully on the newer release.
