The Forge 1.20.1 Version Failed

[TopSigmaMax]

I already said this in a different issue, but the mod isn't working properly. The installation of the mod is fine, the game is running with it, but the zombies aren't working properly. When I shot an arrow and it landed, the zombies just did nothing. I don't have any mods that conflict with the mod, and this mod worked well on previous versions such as 1.18.2. The only thing that's working is the player bleeding out blood when taking damage.
