My squad has been running into this issue constantly about since the patch the Havoc was introduced. Before then, the game was incredibly stable and we almost never crashed.
The crashes often happen after you've won a fight, as that's when you're interacting with the most deathboxes. That means when you're at your best is when you're most likely to be arbitrarily kicked from the game. The heartbreak of it ends play sessions with my friends every time.
I miss long play sessions uninterrupted by random crashing. This game is so amazing when it works... just makes it hurt all the more when it doesn't.
More often than not, it seems to happen with the first deathbox you interact with after a fight. It might have something to do with how fresh the deathbox is, or some kind of condition being activated during the fight that makes it so the next deathbox you open crashes you. Maybe some kind of desync with regards to the state of the deathbox you're opening.
