          <p>@stepan-korchagin</p>
          <p>No, can not reproduce in 2020</p>
          <p>but in previews patch for 2018, there is no problem. Also no problem in 2019 patch A.</p>
          <p>One day, I remember, after update of patch B for 2019, webcam protection became useless for all program, not just QQ. </p>
          <p>After patchC fix the issue( this was mentioned in release note of patchC), only blocking QQ use camera become a problem.</p>
          <p>Webcam protection useless for QQ is not a new bug, I reprot such problem to support approximately a year ago.</p>
