Launcher Crash bug

This has been happening for a while now. I dont know the issue but the launcher keeps crashing and says "An unexpected issue occured and the game crashed." Idk if there is a crash repord but its really annoying because my friends dont have this issue and i think not everyone is affected by this issue. I use Windows 7 and bought Minecraft a month and a half ago and i just want to play again. I hope this helps in any way and i hope it gets fixed soon
