You probably need to run zadig.exe to get the right driver loaded... see ( https://www.rtl-sdr.com/getting-the-rtl-sdr-to-work-on-windows-10/). I believe a copy of zadig.exe should be in the ./gnuradio-3.7/bin directory.
Have you used the rtl-sdr dongle with any other windows applications? If not, I would try to get it running in gqrx that came bundled with gnuradio. That will rule out if it's your gnuradio setup or a driver issue. If it works in gqrx, then which source block are you using and what parameters have you provided to the source block? I suspect it's the driver issue which is easily sorted with zadig (and should only need to be done once).
