This error was not present on 0.3.1, If you need more info please let me know!

Downgrading sodium, indium, and related mods fixed this. Seems to be a compat issue with the latest sodium.

I stand corrected, this issue is the result of a change to my modpack and is still present on 0.3.1,
mod1s.zip
These are the changed mods that I updated/added between this working and not working. Let me know if you need more help!

Would you happen to have the log?

Unfortunately not, it does not seem to be in my log folder, however, I noticed one other change I didn't mark down here : https://modrinth.com/mod/phantom-loader this library was removed from my pack while downgrading sodium.

Interesting. I was looking at my code and it is possible to get a null ref if the client connection process does things out of sequence. I suspect this is what is happening.
