Why does this keep happening? sometimes it will even play the falling animation. I dont want them to collide.

local PhysicsService = game:GetService("PhysicsService")
local Players = game:GetService("Players")

PhysicsService:RegisterCollisionGroup("Characters")
PhysicsService:CollisionGroupSetCollidable("Characters", "Characters", false)

local function setCollisionGroup(character)
	for _, part in pairs(character:GetDescendants()) do
		if part:IsA("BasePart") then
			part.CollisionGroup = "Characters"
		end
	end
end

local function onCharacterAdded(character)
	setCollisionGroup(character)

	-- Listen for changes to descendants
	character.DescendantAdded:Connect(function(descendant)
		onCharacterAdded(descendant)
	end)
end

Players.PlayerAdded:Connect(function(player)
	player.CharacterAdded:Connect(function(character)
		onCharacterAdded(character)
	end)
end)

Please do not ask people to write entire scripts or design entire systems for you. If you can’t answer the three questions above, you should probably pick a different category.

Try adding a small delay so that everything loads.

Players.PlayerAdded:Connect(function(player)
	player.CharacterAdded:Connect(function(character)
		task.wait()
		onCharacterAdded(character)
	end)
end)

When listening for descendants, you’re not setting the collision group of the new descendant if it’s a BasePart. Instead, you check its descendants and set its collision group if it’s a BasePart.

local function onCharacterAdded(character)
	setCollisionGroup(character)
	
	-- Listen for changes to descendants
	character.DescendantAdded:Connect(function(descendant)
		if descendant:IsA("BasePart") then
			descendant.CollisionGroup = "Characters"
		end
	end)
end

I recommend making a script in StarterCharacterScripts instead because for some reason player.CharacterAdded won’t fire when Players.PlayerAdded fires. Any script under StarterCharacterScripts will run when a player’s character loads or respawns.

-- Server Script in StarterPlayer.StarterCharacterScripts
local PhysicsService = game:GetService("PhysicsService")

local Character = script.Parent
local collisionGroup = "Characters"

if PhysicsService:IsCollisionGroupRegistered(collisionGroup) == false then -- in case the collision group hasn't been registered yet (IMPORTANT)
	PhysicsService:RegisterCollisionGroup(collisionGroup)
end

if PhysicsService:CollisionGroupsAreCollidable(collisionGroup, collisionGroup) == true then -- in case Characters is still collidable (IMPORTANT)
	PhysicsService:CollisionGroupSetCollidable(collisionGroup, collisionGroup, false)
end

for _, Limb in ipairs(Character:GetDescendants()) do
	if Limb:IsA("BasePart") then
		Limb.CollisionGroup = collisionGroup
	end
end

Character.DescendantAdded:Connect(function(Limb)
	if Limb:IsA("BasePart") then
		Limb.CollisionGroup = collisionGroup
	end
end)
