[justdomyself]

I use windows system, pycharm。 python3.85.

`from rich import print
from rich.logging import RichHandler
import uvc

def main():

for device in uvc.device_list():

    cap = uvc.Capture(device["uid"])

    for mode in cap.available_modes:
        print(f"{cap.name} running at {mode}")
        try:
            cap.frame_mode = mode
        except uvc.InitError as err:
            print(f"{cap.name} mode selection - {err}")
            continue
        try:
            for x in range(10):
                frame = cap.get_frame_robust()
                print("frame gray mean", frame.gray.mean())
            # print(frame.img.mean())
        except uvc.InitError as err:
            print(f"{cap.name} getting frames - {err}")

    cap.close()`

error message below :
