Bo2 (t6mp) keeps crashing when joining a server

[Dare Rapist]

I'm able to play regular bo2 without the Plutonium launcher but whenever I try to join a server or start a private match game on Plutonium it crashes. Pluto works perfectly fine on T5 and IW5 but not with T6. Any idea on how to fix this?

Here's the crash dump:
