I'm trying to make a win system for my game, but support won't respond. Can anybody help me?

i just need a win system where if there is nobody alive but the killer in the round, it will return everybody into the lobby, but it's being very troublesome with me. Can anybody help?

First, create a list for the players that aren't killers and when they die or leave the game, their name gets removed from the list, and when the list's length is 0, it means that the killers won, make sure to only check for the list length when there is a game running or it might spam the killer winning while players are in lobby
