It's not a crash it is the server ratelimit on packages sent to client.
You need to enable ServerFilter=1 in your eqclient.ini and then remove as many filters in your alt-o settings ingame.
That will stop the dc to char server
This made a improvement for me. Anyone else got more suggestions lol.
Edit - One difference I have noticed with ZP this time around is that things are more of teleporting to me and not pathing so this could be part of why I am getting the packet overload and DCing that I did not have before
