So... I was installing an app, and because it wasn't doing anything whatsoever I closed the installation process in task manager, after that the PC started going really laggy, I checked task manager again and there were a bunch of weird processes, so I started closing them all until Windows told me that an error was encountered and the PC needed to be restarted in one minute, after it restarted all my files were unusable because they all end in .sspq
