Incoming client packet has caused exception

Every time I try to join my friends game it gives me this message. We have no mods installed and I tried creating a new character as well as verifying game files to no avail. I've included the error log. Thank you!

 

The three of us all double-checked mod folders and have nothing installed. All of our games are fresh installs and fully updated. Since posting I have also tried making a new character, reinstalling, and verifying game files none of which worked. It may also be worth mentioning that we each tried to host the game and I was unable to join either of them. However, one of them was able to join my game. Another update- I turned on allowing mismatching assets and now I am getting a different error when I try to join my friend's game. It reads client ship world has errored.
