Server Help Multiplayer through Steam issues

Hi,

I have tried many times to play multiplayer with my friend using Steam to join game. However, I kept getting "
You were disconnected from the server for the following reason:
Incoming client packet has caused exception"

I did not have mods installed for that, I double checked.

To try and resolve the issue, I saved my user data in a different folder and then deleted the user data and info out of the Starbound Storage folder. This allowed me to connect to my friend for all of 10 seconds, which is more than before, however, it threw a different error message the second time around, Fatal error.

Then, I had her try to connect to me and we got a tiny bit further, we were able to hop down into a world for a few seconds. However, she received a completely different error message "Exception caught in client main-loop"

I have attached the screenshots and docs of the error logs and messages.
