I have been dealing with the exact same issue for months for three different PCs, and now it’s getting worse as it’s not only happening to child’s account but also to my laptop/desktop’s initial startup. When it happens during PC startup, you face a black screen with a mouse cursor moving around, nothing else; unlike with the child’s account, you could apply the workaround by holding Ctrl+Alt+Del, signing out and back in in a second attempt; no, there is nothing you can do if it happens at PC startup other than forcing the PC down (by pressing and holding the power button) and reboot the PC. It happens more frequent on my desktop than on my two other laptops, to be precise. Here are my KSK info on one of my laptops: Operating system version & build? (select Windows Search, type winver press enter, the popup will display the information) Version 1909 (OS Build 18363.778) KSK license (Free, Premium, Trial) ? & version ? Premium version 20.0.14.1085 (j) Has a KSK/system requirements check been done? Yes Is “after entering the password & pressing enter, the screen goes black” a new problem or has always existed? Has always existed on three different PCs. If a “dummy” child profile is created, at login, after entering the password & pressing enter, does the screen turn black ? I did created a "dummy" child profile on this laptop and the issue started right after KSK was installed. Are any Windows Parental Control options configured/enabled? No Has your son’s original KSK profile been deleted and a new KSK profile created & the issue tested? Both a laptop and desktop he's using have been re-imaged several times but the issue persists Is there any other Kaspersky software installed? If “yes”, name, version & patch(x)? No May I have a video of the issue please? I can send a picture I took when it happened this week. Has KSK been uninstalled & reinstalled? All three laptops / desktop have been re-imaged several times but the issue follows right after KSK is installed; that being said, there is no such issue without KSK, period. Has the issue ever been logged with Kaspersky Technical Support? Not yet
