I was launching minecraft so I could join my server, Minecraft launched successfully and so I continued to joining my server. I tried to join and Minecraft crashed.

What I did afterwords: 1st I thought it would be a mod I installed yesterday so I removed it. Then I tried closing minecraft and starting it back up and join the server. It still crashed so I was out of ideas. I still have forge installed ( I wasnt using forge at the time of the crash)
