Why does the area capture setting fail?

The following methods should be used in pairs:

• If users only need to capture the desktop screen without filtering windows and only capture the screen area, it is recommended to use: "zego_screencapture_set_target_screen" and "zego_screencapture_set_target_rect".
• If users need to capture windows, window areas, filter windows, capture screens and need to filter windows, it is recommended to use: "zego_screencapture_set_target_window" and "zego_screencapture_set_target_window_rect".
