Can't load the mod
I've got this error every time I launch the game :

NullReferenceException: Object reference not set to an instance of an object

Any idea for what it means ?

Fix the mod, it's crashing:

I was also still encountering this error. To fix it, I ended up navigating to
%USERPROFILE%\Documents\Klei\OxygenNotIncluded\mods\Local\MultiplayerMod
There I found a Local folder and a Steam folder. I noticed that the timestamps on my Local folder files were up to date, but the Steam folder files were not. To fix, I simply manually copy and replaced the files in the Steam folder with the files in my Local folder. Then, the game was able to launch without errors. That said, in my Mods I now have two instances of the multiplayer mod with the same version.

Things I tried before the above that were not successful:
  1. I tried re-installing the mod using the bat file from the github page install instructions.
  2. I tried uninstalling and re-installing the base game through steam.
  3. I made sure that video drivers, etc. were also up to date.
  4. I tried unsubscribing and re-subscribing to the mod.

Thanks for all your answers ! I was too impatient so after trying different solutions and failing. I've downloaded the mod from the creator's github and it worked !
I guess I'm going to go on with the github mod 😁
