I load the launcher and click "Play", a long load, then the play button grays out and I can't click it and it just sits there

What I expected to happen was to be able to be able to play Minecraft

What actually happened was it grayed out the "Play" button and I couldn't

Steps to Reproduce:
1. Load the Minecraft Launcher
2. Click "Play"
3. Let it load
4. Notice that you can't actually play (grayed out "Play" button and nothing happening)
