The multiplayer simply does not work :/

The multiplayer provided by the dev is not fit for newer/upcoming windows updates, which makes me want to hold down n slow the rate at which i update my windows 11 at… but that seems to not help in any way with my situation or any of the other apps that are in tune with the newer updates.

I have tried several different outside mods/hacks to make it work aswell, but those seem to have the same outcomes as the normal mod itself does…
