I dont know if its something wrong with npcs but in singleplayer when ı waer mask they will stop attacking me but in mulitplayer they not stopping and keep attacking me my other friends have this problem too

It's not supposed to work in multiplayer.
It causes an error and if two or more people use it at once, things can get problematic.
If one person uses it at a time, and you are okay with a lua error, it should be sustainable.
Quentin must've forgotten to put that in the description, but we never originally designed it for multiplayer.
