You’ll break things if you do more and more stuff suggested inside this thread without testing it. Maybe executing ldconfig was enough, but if you try more and more stuff you don’t know what you did. Linux is very hard to break, especially when you didn’t mess around with things like packages and libraries by yourself, there’s mostly a way back. But if you’re scared use the time and make a backup and a live USB stick with a Linux distro of your choice to rescue the system if something’s terribly messed up.
