Common fault under Windows10 is the incorrect detection of 2 devices perceived as SDR devices. The real SDR is often the 2nd un-selected by default one
Found 2 device(s):
0: T■, ©■, SN: T (currently selected)
1: Realtek, RTL2838UFA, SN: 00001000
usb_open error -12
Error opening the RTLSDR device: No error
