I'd say either reinstall MC (BACK UP FIRST, I'll say it again, MAKE SURE TO BACK UP .mincraft before you delete it) or try using MultiMC. If MultiMC doesn't work, I'd say it's probably an issue with your account. Also, that is not a crash report, and this is not a bug. I'll move it to the appropriate forum.
