Crash

I played three days ago and Minecraft was fine. Now it crashes. It used to crash right as I clicked Play on the launcher but I disabled the Java Arguments in the profile and now the main menu shows up but when I open a world/server it crashes.

Crash when clicking on the us.mineplex.com server. (It crashes on all servers and worlds)
