how do i fix this problem while making a npc ai and using body gyros ?

im making a npc ai, and im having a problem that one of the npcs works perfectly fine and the other one just spins like crazy, im using body gyro but it doesn't seems to work ?

here's my code

local crocs = true
local cro = true
local cr = false

local function sue()
	if cr == true then return end
	local timeo = math.random(1,8)
	wait(timeo)
	cro = true
	cr = false
end

function lookAt(chr,target) --assume chr is a character and target is a brick to look towards
	if chr.PrimaryPart then --just make sure the character's HRP has loaded
		local chrPos=chr.PrimaryPart.Position --get the position of the HRP
		local tPos=target.Position --get the position of the target
		local modTPos=Vector3.new(tPos.X,chrPos.Y,tPos.X) --make a position at the target, but with the height of the character
		local newCF=CFrame.new(chrPos,modTPos) --create our CFrame
		chr:SetPrimaryPartCFrame(newCF) --set the HRP's CFrame to our result, thus moving the character!
	end
end

script.Parent.Target.Changed:Connect(function()
	if script.Parent.Target.Value ~= nil then
		crocs = false
		local target = script.Parent.Target.Value
		local myhuam = script.Parent.Humanoid
		while crocs == false do
			wait()
			sue()
			script.Parent.HumanoidRootPart.BodyGyro.CFrame = CFrame.new(script.Parent.Torso.Position - Vector3.new(0,script.Parent.Torso.Position.y,0),target.HumanoidRootPart.Position - Vector3.new(0,target.HumanoidRootPart.Position.y,0))
			--script.Parent.HumanoidRootPart.BodyGyro.CFrame = CFrame.new(script.Parent.Torso.Position - Vector3.new(0,script.Parent.Torso.Position.y,0),target.HumanoidRootPart.Position - Vector3.new(0,target.HumanoidRootPart.Position.y,0))
			cr = true
			local move = math.random(1,3)
			if cro then
			if move < 3 then
					local moto = math.random(-3,3)
					local offset = Vector3.new(moto,0,-8)
				local pos = target.Torso.CFrame*CFrame.new(offset).Position
				myhuam:MoveTo(pos)
				end
			end
			if not cro then
				if move == 3 then
					myhuam:MoveTo(target.Torso.Position)
				end
			end
		end
	else
		crocs = true
	end
end)

and here's a gyazo gif of the problem

the MaxTorque of both body gyros are 0,10000,0 the P is 3000 and the D is 500
