windows 10 x64 KTS 21.3.10.391 (d) I´ve been using KTS for years, but 10 days ago, DURING the time I was using the pc, the browser stop access sites, then I notice that other programs also can´t connect. But some programs works fine, like Steam, Firefox, discord. Others don´t, like Opera, Chrome, Whatsapp desktop, OBS… Then after a lot of trying, stoping KTS allows everything to work properly.
