Nothing worked, I have this issue since the Windows 11 24H2 update. After I deinstalled the update back to the 23H2 update, everything was/is working smoothly and perfectly again. I tried really everything you said, as well as everything that is mentioned here > Why is my Studio Lagging? - #3 by Vyntrick I ofc also tried resetting settings, reinstalling studio, everything but nothing works unless going back to the windows 23H2 update.
