I clicked play, and after the launcher dissappeared, It would reappear and give a crash report.

It said as follows:

Minecraft Crash Report ----

What I expected to happen was the game would launch and I could enjoy Minecraft.

What actually happened was the launcher crashed and the game wouldn't load.

Steps to Reproduce:
1. What I did was I made a copy of my profile
2. Launched the game
3. Crash report came up
