Hey! I'm a complete newbie when it comes to anything like this, but I have been experiencing the same problem, and I've found a manual, but not permanent, fix. After pressing Launch the Minecraft app doesn't appear of course, but if you go in to Task Manager, scroll down until you find both the instances of the minecraft launcher, by closing the bottom one with more memory usage, it closes both of them and makes the Minecraft window. Hope this helps! Still waiting for a permanent fix, because having to do this every time I want to play Minecraft is quite the pain!
