      Is that issue also actual for 2020?

      Looks like it is not patch issue, because it also present for 2018

        No, can not reproduce in 2020

        but in previews patch for 2018, there is no problem. Also no problem in 2019 patch A.

        One day, I remember, after update of patch B for 2019, webcam protection became useless for all program, not just QQ.

        After patchC fix the issue( this was mentioned in release note of patchC), only blocking QQ use camera become a problem.

        Webcam protection useless for QQ is not a new bug, I reprot such problem to support approximately a year ago.

                        update to patch C again

                        It is miracle that I cannot reproduce again.

                        webcam protection work fine on uwp camera app and QQ.

                        I do not know why, but the problem is no more reproduced.......
