Change camera size fails on windows, works on linux?

edit

This codeworks on Linux, it Fails on windows10 OpenCV 3.4.2, 64bit -Python 3.6 - installed via "pip3 install opencv-python"

It fails on Windows with the error message below.

If I remove the 'cv2.set()' for the horz and virt size it works, without problem but the resolution is not what I want

My goal is to change from the default camera image size to the LARGER size.

v=3.4.2
Camera H=480, W=640
Camera H=480, W=640
[ WARN:0] videoio(MSMF): OnReadSample() is called with error status: -1072875855

[ WARN:1] videoio(MSMF): can't grab frame. Error: -1072875855
[ WARN:1] videoio(MSMF): can't grab frame. Error: -2147483638

This is the Python code

import cv2
print("v=%s" % cv2.__version__)
cap = cv2.VideoCapture(0, cv2.)
h = cap.get( cv2.CAP_PROP_FRAME_HEIGHT )
w = cap.get( cv2.CAP_PROP_FRAME_WIDTH )
print("Camera H=%d, W=%d" % (h,w) )
# If I remove these two lines it works but is stuck at 640x480
cap.set( cv2.CAP_PROP_FRAME_HEIGHT, 10000 )
cap.set( cv2.CAP_PROP_FRAME_WIDTH, 10000 )
h = cap.get( cv2.CAP_PROP_FRAME_HEIGHT )
w = cap.get( cv2.CAP_PROP_FRAME_WIDTH )
print("Camera H=%d, W=%d" % (h,w) )

while(True):
    if cv2.waitKey(1) & 0xFF == ord('q'):
        break
    ret, frame = cap.read()
    if ret:
        cv2.imshow('frame',frame)

cap.release()
cv2.destroyAllWindows()
