Animations stuttering issue

1. What do you want to achieve? Keep it simple and clear!
   a run system, with stamina and animations

2. What is the issue? Include screenshots / videos if possible!
   the animations keep bugging out, for some reason

3. What solutions have you tried so far? Did you look for solutions on the Developer Hub?
   yes, i have tried multiple solutions, and nothing worked

what code are you using to play the walk animations

also maybe the animation length has to match the default walk animation length of 1 second

the code im using to play the animations i here

rs.Heartbeat:Connect(function(DeltaTime)
	if walk.IsPlaying then
		print("Walk")
	end
	if run.IsPlaying then
		print("Run")
	end
	if humanoid.MoveDirection.Magnitude == 0 then --if the movedirection is equal to 0 then the following will happen;
		moving = false
	elseif humanoid.MoveDirection.Magnitude > 0 then --if the movedirection is greater than 0 then the following will happen;
		moving = true
	end
	if (rootpart.CFrame.LookVector:Dot(humanoid.MoveDirection)) <= -0.65 then
		run:AdjustSpeed(-0.85)
		walk:AdjustSpeed(-1)
		runningback = false
	else
		runningback = true
		run:AdjustSpeed(1)
		walk:AdjustSpeed(1)
	end	
	if running then
		if stamina > 0 then
			stamina = stamina - staminaloss * DeltaTime
		else
			exhausted = true
		end
	elseif stamina < 100 then
		stamina = stamina + staminaloss * DeltaTime
		if stamina > RunRefresh then -- we can now run again!
			exhausted = false
		end
	end
	staminabar.Size = UDim2.new(stamina/maxsize,0,1,0)	
	if moving then
		if running and not exhausted then
			walk:Stop()
			if not run.IsPlaying then
				run:Play(.2)
			end
			if runningback then
				humanoid.WalkSpeed = sprintspeed * 0.85
			else
				humanoid.WalkSpeed = sprintspeed
			end
		else
			run:Stop()
			if not walk.IsPlaying then
				walk:Play(.2)
			end
			humanoid.WalkSpeed = walkspeed
		end
	else
		run:Stop(.2)
		walk:Stop(.2)
	end
end)

it may be bad but i dont know what went wrong

I figured out the issue

it was that there already was an animator instance
