Hello there @grimsituation6!
Thank you for taking the time to reach out to us!
We are aware of a situation occurring where some assets were coming up invisible and we have released a new patch in the meantime.
You can find the patch notes for this patch here.
However, in relation to crashing and VoIP, could you please provide me with further details? Are you playing on an official server? If so, which server?
Please let us know if the situation persists after patching the game.
