Windows Realtek USB wireless network card boot failure Rtlihvs. DLL module stop problem

June 4, 2020 Update:
Another reason was found that the USB wireless network card of the chip could not be connected to the USB interface of the monitor (USB interface is provided on the AOC monitor of the blogger).
It is speculated that the network card device could not be successfully initialized due to insufficient power supply of THE USB interface on the display when the system started. In this case, the network card can only be directly inserted into the host computer.
Or buy a separate USB extension cord and place it on the desktop (it may cause signal problems if some partners plug it into the host).

Problem description
After booting up, the wireless network card does not start successfully. When entering the device manager, you can see that the network card is marked as warning. The device can be successfully activated and used by disabling and enabling the device.
