Weird. I play multiplayer every night, but only crash with lightning guns. And apparently they are patching that today. Hopefully they fix whatever is causing your crashes as well!

Disable or reduce the screen shake effect in your settings. This was a major source of crashing for me.

Not sure if that one was also addressed in this patch, but teammates causing huge screen shakes (usually by landing a Hellpod right next to me) would cause me to instantly crash, or sometimes be transferred immediately back into my ship by myself if I was lucky enough to not fully crash the game when it happened. I've had far fewer crashes, even with people landing Hellpods next to me, since lowering the shake effect.
