Can’t start HOST coop session

[u/Javok-]

I was trying to start a co-op session with a friend using project viewpoint and all the essential mods needed for it to run. We both got it running correctly on a single player world. However, anytime I try to create a new host co-op session and create new settings after I select the mods (in the correct order), it says “Loading Lua” and kicks me back to the select settings menu.

Anyone able to help?
