Just before i lock this and ban the player i would like to know how you were able to hit him at the lobby for mini games?
Oh, there is a glitch in bedwars where after the timer ends it doesn't teleport you in game and it keeps everyone in the lobby. This allows players to PvP because the game technically started even though everyone is still in the lobby. Also, after you die you teleport to your island but none of the generators work so it renders the game useless. I don't know why this happens, but I believe something happens to the first player when they join and it glitches the timer, therefore causing the whole thing.
