Issues with serverside mod (SOLVED)

I'm trying to make a simple mod that works server or clientside - if you have it on your client it works fine, but if you join a modded server without it it also works.

The mod doesn't have any assets or clientside features, to my knowledge. I also made sure to add the line

ModLoadingContext.get().registerExtensionPoint(ExtensionPoint.DISPLAYTEST,() -> Pair.of(()-> FMLNetworkConstants.IGNORESERVERONLY,(a,b)->true));

from the docs, to ensure it worked. However, even when the player joins with the mod, the server reports 'failed to synchronize registry data minecraft'. It might have something to do with the config files? But even then the config is set up as the SERVER type, so I would assume it doesn't need to match.

All the mod does is register a block break event handler, a server config file, and a single command.

Does anyone know what the issue could be?

I'm stupid, I accidentally deleted a mod on my client while developing the mod. Sorry about that
