I'm going to guess MorePlayerModels is a client side mod, remove it from your server and see what happens.

[AjaxOfTheDead]

well MorePlayerModels is the only mod on the server rn but i've tried to use other mods and they dont work either

[AjaxOfTheDead]

here's the log without any mods

Post a log of a crash with other mods.

 

And a dedicated server is not aware of any client-side classes (they don't exist), so mods that access them, while they will often work playing single player, since the client and server both exist, if they are put on a dedicated server they will crash it because it cannot load any client related classes. So, even with no other mods, one of these will crash a server.

[AjaxOfTheDead]

i added a mod that doesnt involve my client and it works now
