Launcher won't start when opening Minecraft.app

When I try to open Minecraft.app, it doesn't "bounce," or anything like that, and the launcher doesn't open (I attached a video of me trying to open it).

In Terminal, I opened /Applications/Minecraft.app/Contents/MacOS,

then ran ./launcher. It opened the launcher fine through this method. 

I've also tried restarting my computer a few times. The launcher opens fine using the normal method the first/second time, but after that, it doesn't work anymore until the computer restarts again.
