Plutionium T4 Crash Report

[aap2]

Hi, so i keep getting this error when trying to join a server, this crash randomly happened one day when trying to play T4 Multiplayer.

This seems to be an unknown error since i haven't seen anything about it on the forums or anywhere online.

if anyone could help me resolve this issue, thanks
