Windows 10: Many apps are crashing, windows start menu not working properly

I was facing a problem with launching emulator on android studio, for it, on the internet, the solution was to unhide C:\Users\username\AppData and its content. But after I restarted AppData again hid itself with all content inside it. Before only certain folders were hidden inside AppData, but now every one of them is hidden and if I unhide them, they hide themselves again. Because of this I cant launch apps via the start menu, the start menu search bar crashes sometimes, I cant pin things to the taskbar, many apps are showing fatal errors. Help.
