1.9 Crash when opening world or logging in to server

Upon either opening a single player world or logging in to a server my copy of MC 1.9 crashes immediately. This happens both on the vanilla launcher and MultiMC. Logging into the same servers in 1.8.9 works normally. I have tried the Mineplex server and at least three worlds. I have attached my latest crash dump from MultiMC and the vanilla launcher.
